HMC195
GaAs MMIC SOT26 T/R
SWITCH, DC - 2.5 GHz
Features
Low Insertion Loss: 0.4 dB
Ultra Small Package: SOT26
High Input IP3: +62 dBm
Positive Control: 0/+3V to 0/+8V
General Description
The HMC195 is a low-cost SPDT switch in a
6-lead SOT26 package for use in transmit or
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 with less than 1 dB loss. The
design provides exceptional intermodulation performance; a +62 dBm third order intercept at
8 Volt bias. RF1 and RF2 are refl ective 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.
