Functional Diagram
General Description
The HMC154S8 & HMC154S8E are low-cost SPDT
switches in 8-lead SOIC packages for use in transmit-
receive applications which require very low distortion
at high signal power levels. The device can control
signals from DC to 2.5 GHz and is especially suited for
900 MHz and 1.8 - 2.2 GHz applications. The design
provides exceptional intermodulation performance;
providing a +60dBm third order intercept at 8 Volt bias.
RF1 and RF2 are reflective shorts when “Off”. On-chip
circuitry allows single positive supply operation at very
low DC current with control inputs compatible with
CMOS and most TTL logic families.
