Typical Applications
The HMC174MS8 is ideal for:
ISM Applications
PCMCIA Wireless Cards
Portable Wireless
The HMC174MS8 is a low-cost SPDT switch in
an 8-lead MSOP package for use in transmit-
receive applications which require very low dis-
tortion at high signal power levels. The device
can control signals from DC to 3.0 GHz and is
especially suited for 900 MHz, 1.8 - 2.2 GHz, and
2.4 GHz ISM applications with only 0.5 dB loss.
The design provides exceptional intermodulation
performance; providing a +60 dBm third order
intercept at 8 Volt bias. RF1 and RF2 are refl ec-
tive 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.

Notes:
1. Set logic gate and switch Vdd = +3V to +5V and use HCT series logic to provide a TTL driver interface.
2. Control inputs A/B can be driven directly with CMOS logic (HC) with Vdd of 3 to 8 Volts applied to the CMOS
logic gates and to pin 4 of the RF switch.
3. DC Blocking capacitors are required for each RF port as shown. Capacitor value determines
lowest frequency of operation.
4. Highest RF signal power capability is achieved with V set to +10V. The switch will operate properly (but at lower
RF power capability) at bias voltages down to +3V.
