Functional Diagram
General Description
The HMC574MS8 & HMC574MS8E are low-cost
SPDT switches in 8-lead MSOP packages for use
in transmit/receive applications which require very
low distortion at high incident power levels. The
device can control signals from DC to 3 GHz and
is especially suited for Cellular/3G infrastructure,
WiMAX and WiBro applications with only 0.3 dB
typical insertion loss. The design provides 5 watt
power handling performance and +65 dBm third
order intercept at +8 Volt bias. RF1 and RF2 are
reflective shorts when “Off”.

Typical Application Circuit
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 Vdd set to +8V. The switch will operate properly (but at lower RF power
capability) at bias voltages down to +3V.

Evaluation Circuit Board

List of Materials for Evaluation PCB 104124 [1]
The circuit board used in the final application should
be generated with proper RF circuit design tech-
niques. Signal lines at the RF port should have 50
ohm impedance and the package ground leads and
package bottom should be connected directly to the
ground plane similar to that shown above. The eval-
uation circuit board shown above is available from
Hittite Microwave Corporation upon request.
