MICROWAVE CORPORATION HMC427LP3 v05.0604 GaAs MMIC POSITIVE CONTROL TRANSFER SWITCH, DC* - 8.0 GHz Typical Applications Features The HMC427LP3 is ideal for: High Isolation: 40 ~ 45 dB thru 6 GHz • Test Instrumentation Low Insertion Loss: 1.2 dB@ 6 GHz • Fiber Optics & Broadband Telecom Non-Reflective Design • Basestation Infrastructure 3 mm x 3 mm x 1 mm SMT Package • Microwave Radio & VSAT • Military Radios, Radar, & ECM Functional Diagram The HMC427LP3 is a low loss broadband positive control transfer switch in a leadless surface mount package. 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. SWITCHES - SMT 14 * Blocking capacitors are required at ports RF1, 2, 3, & 4. Their value will determine the lowest transmission frequency.
