Description

The 1GC1-4065 is a 1:1 balun for microwave applications over the 3.4 to 16 GHz frequency range. It is fabricated using the Keysight Technologies, Inc. InGaP/GaAs HBT process. A single balanced 50 ohms output, or two unbalanced 25 ohm outputs can be optained from the balun. A typical application is the generation of +LO and -LO signals from a single LO input in the 3.4 to 16 GHz frequency range.

ApplicationsThe 1GC1-4065 1:1 balun is designed for use in microwave communication systems in the 3.4 to 16 GHz operating frequency range.

Operation

The 1GC1-4065 1:1 balun can be utilized to generate either a balanced 50 ohm output, or two out-of-phase 25 ohm unbalanced outputs.

The most common application is the generation of +LO and -LO signals to drive high dynamic range mixers with 3.4 to 16 GHz LO requirements.

Assembly Techniques

Epoxy die-attach using conductive epoxy or solder die-attach using a fluxless AuSu solder preform can be used for assembly. Gold thermosonic wedge bonding with 0.7 mil diameter Au wire is recommended for all bonds. Tool force should be 22 ±1 gram, stage temperature should be 150 ±2 °C, and ultrasonic power and duration should be 64 ±1 dB and 76 ±8 msec, respectively. The bonding pad and chip backside metallization is gold.

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 all substances except for cadmium which is less than 100 ppm by weight.
