Description

The 1GG7-8251 is a GaAs monolithic microwave integrated circuit (MMIC) fabricated using the Keysight Technologies, Inc. GaAs FET process and is designed for low insertion loss and high isolation from DC to 8 GHz. It is intended for use as a general–purpose, single-pole, double-throw (SPDT), absorptive switch. Two series and two shunt MESFETs per throw provide 1.4 dB maximum insertion loss and 38 dB typical isolation at 6 GHz. The IC is packaged with an LED in a plastic molded 3 x 3 mm QFN SMT package.

ApplicationsThe 1GG7-8251 can be used in instrumentation, communications, radar, ECM, EW, and many other systems requiring SPDT switching. It can be used for pulse modulation, port isolation, transfer switching, high-speed switching, replacement of mechanical switches, and so on.

Tape and Reel

The 1GG7-8251 component is available in tape and reel format. See Figures 1 and 2.

Moisture Compatibility

Injection mold components are moisture-sensitive. The product is tested to the Moisture and Reflow Sensitivity Level 3 as per IPC/Jedec J-STD-020 and must be mounted within 168 hours of opening the shipping container. Store and handle parts for reflow and for rework per IPC/Jedec J-STD-033B. See Figure 3.

RoHS Compliance

This device is RoHS Compliant. This means the component meets the requirements of the European Parliament and the Council of the European Union Restriction of Hazard-ous Substances Directive 2011/65/EU, commonly known as RoHS. The six regulated substances are lead, mercury, cadmium, chromium VI (hexavalent), polybrominated biphenyls (PBB) and polybrominated biphenyl ethers (PBDE). RoHS compliance implies that any residual concentration of these substances is below the RoHS Directive’s maximum concentration values (MVC); being less than 1000 ppm by weight for allsubstances except for cadmium which is less than 100 ppm by weight.

Assembly Techniques

The QFN SMT package is compatible with industry standard solder-reflow attach processes.

The GaAs MMIC incorporated in the 1GG7-8251 SMT package solution is ESD sensitive. ESD preventive measures must be employed in all aspects of storage, handling, and assembly.
