Typical Applications
The HMC226 is ideal for:
900 MHz ISM/Cellular
1900 MHz PCS
The HMC226 is a low-cost SPDT switch in a 6-lead
SOT26 package for use in transmit-receive applica-
tions 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 - 2.0 GHz applications with 0.5 to
0.8 dB loss. The design provides exceptional P1dB
and intermodulation performance; a +35 dBm 1dB
compression point and +55 dBm third order inter-
cept at +3 volt bias. RF1 and RF2 are refl ective
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.

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.

Evaluation Circuit Board
GaAs MMIC +3V SOT26 TRANSMIT/
RECEIVE SWITCH, DC - 2.0 GHz
The circuit board used in the fi nal 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 evalu-
ation circuit board shown above is available from
Hittite Microwave Corporation upon request.
