The HMC641A from Analog Devices is a non-reflective GaAs PHEMT SP4T switch that operates from DC to 18 GHz. This switch offers a high isolation of 42 dB, low Insertion loss of 2.1 dB and P1dB of 25 dBm. It operates using a negative control voltage of 0/-5V and requires a fixed Vss bias of -5V. This switch also includes an on board binary decoder circuit which reduces the number of required logic control lines to two. The HMC641A is available as a bare die which measures 1.92 x 1.60 x 0.10 mm and is ideal for Telecom Infrastructure, Microwave radio, VSAT and Test Instrumentation applications.
