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 & HMC195E are low-cost SPDT switches
in 6-lead SOT26 packages 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 intermod-
ulation performance; a +62 dBm 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.
