General Description
The HMC284MS8G is a low-cost SPDT
switch in an 8-lead grounded base MSOP
package. The device can control signals
from DC to 3.5 GHz and is especially suited
for Cellular, PCS, 2.4 GHz ISM, and 3.5
GHz WLL frequency bands. The design
has been optimized to provide high isolation with minimal insertion loss for medium
and low power applications. On-chip circuitry allows positive voltage control operation at very low DC currents with control
inputs compatible with CMOS and most
TTL logic families. In the "OFF" state, RF1
or RF2 is non-reflective. Applications include local oscillator or receive antenna
multiplexing in cellular/PCS base station
applications. See reflective high isolation
SPDT version, HMC194MS8.
