HMC232

The HMC232 is a broadband non-refl ective GaAs MESFET SPDT MMIC chip. Covering DC to 15 GHz, the switch features over 55 dB isolation at lower frequencies and over 45 dB at higher frequencies due to the implementation of on-chip via hole structures. The switch operates using two negative control voltage logic lines (A&B) of -5/0V and requires no Vee. Alternate A & B control pads are provided to ease MIC implementation. All data shown is tested with the chip in a 50 Ohm test fi xture connected via 0.025 mm (1 mil) diameter wire bonds of 0.5 mm (20 mils) length. This HMC232 is a form, fi t & functional replacement for the HMC132.
