Surface Acoustic Wave (SAW) devices are components that make use of the ability of piezoelectric materials to convert acoustic (i.e. mechanical) waves into electromagnetic signals, and vice-versa. By far, the most common SAW devices are those which perform a filtering operation, also known as SAW filters. SAW Band Pass Filters (SAW BPF) sort signals by frequency the most widely used substrates being quartz (SiO2), lithium niobate (LiNbO3) and Lithium tantalite (LiTaO3) that are very brittle materials.

Usually SAW filters operate from 600 MHz to 2 GHz frequency range in mobile environment. Based on IF (Intermediate Frequency) and RF (Radio Frequency) filtering, there are two types of filters, IF SAW and RF SAW filters. In addition, based on construction, there are different  types of offered SAW filters such as IIDT, DMS and ladder.

Main advantages or benefits of SAW filters include:

• they allow electro-acoustic coupling via the transducer

• SAW velocity is 105 times less than that of Electromagnetic (EM) wave. As a result, SAW filters can be used in cases where EM wave based filter designs are impractical to be developed

• SAW filters are less expensive compared to BAW (Bulk Acoustic Wave) filters

• SAW filters are easy in fabrication due to easy access to their structure from the above surface of the filter.

The selection of the right SAW filter for an intended application is based on significant parameters like those listed below. Such filters are produced by different manufacturers such as TAI-SAW, Qualcomm, API, Golledge Electronics, Oscilent, Amplitronix LLC, Vectron, Filtronetics, Microsaw, SAWTRON and others.

• RF or IF type

• RF center frequency

• Bandwidth

• Pass band ripple (dB)

• Power handling capability

• Insertion loss in pass band (dB)

• package type and dimension

MIL-DTL-38999 Series I Connectors are high-performance cylindrical connectors used on  aerospace and other applications. Sourced from reliable manufacturers such as AMPHENOL, TE CONNECTIVITY, CORSAIR and others they are offered in different sizes,  shell styles, materials and finishes. Designed for rugged reliability, they provide excellent vibration, corrosion and shock resistance, and offer excellent EMI protection and shielding effectiveness. Please refer to the supplied documentation for additional information.

MIL-DTL-26482 Standard Series II connectors are widely used on applications in aerospace environments requiring a general-purpose, miniature cylindrical bayonet connector.They are environmentally sealed and offered different receptacle-mounting styles.

AMPHENOL Bayonet Neill Concelman (BNC) product series connectors are miniature quick connect RF connectors. They feature two bayonet lugs on the female connector. BNCs are ideally suited for termination on miniature and subminiature coaxial cable (RG-58, 59, to RG-179, RG-316, etc.). Other BNC series include:

HD-BNC product series featuring the trusted, push and turn interface of a traditional BNC and providing tactile feedback and a positive lock for quick and guaranteed mating and 

Mini-BNC product series allowing higher connector densities while preserving the positive characteristics of the full-size 75 Ω BNC. The Mini-BNC provides the same positive locking bayonet system found on the BNC but allows 40% more interconnects in the same area.

Amphenol MS MIL-C-5015 Circular Plug Connectors are designed to meet the demanding performance requirements of military standards. These cable mount circular plug connectors have proven electrical capability for equipment applications where durability is important. The Amphenol plugs have threaded couplings and single key/keyway shell polarization for an accurate and reliable connection. The solid shells of these MS Series circular MIL-C-5015 connectors are made from high grade aluminium alloy. The shells are electrically zinc plated with an olive drab chromate finish which ensures a high resistance to corrosion. The inserts of these military circular connectors are made from resilient synthetic rubber which offers a high dielectric strength and resistance to vibration.

The MS3106A-10SL-3S plug can be used with Turn Coordinator TC02E-3-2 or Turn & Bank Indicator TB02E-2-1.

4-Pin connector by AMPHENOL for use in all electrical gyros (DG or Horizon) including Falcon models.

RG 400 (aka M17/128*) cables are high temperature coaxial cables used in a wide variety of military and commercial applications.

Sourced from quality suppliers, these cables are offered as part of our own label (AVIATIONEU NEW ERA) product lines and are intended for use in tactical operations and aerospace applications. They are are double shielded and made from dielectric PTFE (Polytetrafluoroethylene) material and fluorinated ethylene propylene (FEP) Type IX sheath with a solid copper stranded wire silver-plated conductor. They feature an impedance of 50 +/-2 ohms and an operating temperature range -55 °C ... +200 °C. They are priced and sold in feet. They come with Certificate of Conformance (CoC) and test reports. For additional information please refer to the supplied documentation

(*) M17/128 is a military part number used as equivalent to the RG400 cable. The the specifications and testing of military coaxial cables, including RG400, are very rigorous requiring their manufacturers to test attenuation and structural return loss by sweeping 22 different 50-ohm cables over the frequency band for which their use is recommended.

Connectors are used on electrical wiring harnesses and are essentially enclosures (i.e., shells) which house contacts with wires. The electrical connection into the system at the contact termination is either a soldered or crimped connection (the latter removable from the connector with the use of a special tool). The shell and insert may be moisture resistant or a hermetic seal. The inserts in each connector must be oriented for correct mating, and the shell or insert usually contains a keying feature to prevent miss-mating that could damage the connector or result in an electrical problem. 

Connectors can be of a Plug (“male”) or Receptacle (“female”) type. Receptables are also termed as sockets or jacks. Plugs have prolonged connecting pins which fit into the mating sockets. Receptables have mounting features such as a flange with holes. Connectors used in aircraft are mostly those complying with Military Standards (MIL-STD) and Military Specifications (MIL-SPEC).

Different connectors, structured in series, are offered as part of our own branded (AVIATIONEU NEW ERA) product lines to provide cost-effective solutions for a variety of applications. Sourced by quality suppliers, they are available in plug or receptable types.
