Functional Diagram
General Description
The HMC226 & HMC226E are low-cost SPDT swit-
ches in 6-lead SOT26 packages for use in transmit-
receive applications which require very low distortion
at high signal power levels. The device can control
signals from DC to 2.0 GHz and is especially suited
for 450 MHz, 900 MHz, and 1.8 - 2 GHz applications
with 0.5 to 0.8 dB loss. The design provides excep-
tional P1dB and intermodulation performance; a
+35 dBm 1dB compression point and +55 dBm
third order intercept at +3 volt bias. RF1 and RF2
are reflective opens 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.

Typical Application Circuit

SWITCHES - SMT
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.
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.
