HMC427LP3 / 427LP3E v07.0805 GaAs MMIC POSITIVE CONTROL TRANSFER SWITCH, DC* - 8 GHz Typical Applications The HMC427LP3 / HMC427LP3E is ideal for: • Test Instrumentation • Fiber Optics & Broadband Telecom • Basestation Infrastructure • Microwave Radio & VSAT • Military Radios, Radar, & ECM Features High Isolation: 40 ~ 45 dB thru 6 GHz Low Insertion Loss: 1.2 dB@ 6 GHz Non-Reflective Design 3 x 3 mm SMT Package Functional Diagram General Description The HMC427LP3 & HMC427LP3E are low loss broadband positive control transfer switches in leadless surface mount packages. Covering DC to 8 GHz, this switch offers high isolation and low insertion loss. The switch operates using a positive control voltage of 0/+5V and requires a fixed bias of +5V @ < 20 μA. 10 SWITCHES - SMT * Blocking capacitors are required at ports RF1, 2, 3, & 4. Their value will determine the lowest transmission frequency.
