HMC226 v02.0502 MICROWAVE CORPORATION GaAs MMIC +3V SOT26 TRANSMIT/ RECEIVE SWITCH, DC - 2.0 GHz Typical Applications Features The HMC226 is ideal for: Low Insertion Loss: 0.6 dB • 900 MHz ISM/Cellular Ultra Small Package: SOT26 • 1900 MHz PCS High Input P1dB: +35 to +38 dBm High Input IP3: +55 to +61 dBm Positive Control: 0/+3V to 0/+8V Functional Diagram General Description The HMC226 is a low-cost SPDT switch in a 6-lead SOT26 package 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 - 2.0 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 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.

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.
