HMC224MS8
GaAs MMIC T/R SWITCH
5.0 - 6.0 GHz
Features
Low Cost 5-6 GHz Switch
Ultra Small Package: MSOP8
High Input P1dB: +33 dBm
Single Positive Supply: +3 to +8V
General Description
The HMC224MS8 is a low-cost SPDT switch in
an 8-lead MSOP package for use in transmitreceive applications. The device can control signals from 5.0 to 6.0 GHz and is especially suited
for 5.2 GHz UNII and 5.8 GHz ISM applications
with only 1.2 dB loss. The design provides exceptional power handling performance; input P1dB =
+33 dBm at 5 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. No DC blocking
capacitors are required on RF I/O ports.

7. ALL GROUND LEADS MUST BE SOLDERED TO PCB RF GROUND.
Typical Application Circuit
SWITCHES - SMT
Notes:
1. Control Inputs A and B can be driven directly with CMOS logic
(HC) with V of 3 to 8 Volts applied to the CMOS logic gates
and to pin 4 of the RF switch.
2. Set V to 5 Volts and use HCT series logic to provide a TTL
driver interface.
3. Highest RF signal power capability is achieved with V set to
+10V. However, the switch will operate properly (but at
lower RF power capability) at bias voltages down to +3V.
4. RF ByPass: Do not use RF bypass capacitors on Vdd, A or B
ports. Resistors R1, R2, R3 = 100 Ohms should be placed
close to the Vdd, A and B ports. Use resistor size 0402 to
minimize parasitic inductances and capacitances.
5. DC Blocking capacitors are not required for each RF port.
6. Evaluation PCB available.

The circuit board used in the fi nal application
should be generated with proper RF circuit design
techniques. Signal lines at the RF port should
have 50 ohm impedance and the package ground
