HMC446 / 446E v03.0805 GaAs MMIC 10W T/R SWITCH, 824 - 894 MHz* Typical Applications Features The HMC446 / HMC446E is ideal for: Low Insertion Loss: 0.6 dB * ISM/Cellular Portables/Handsets High IIP3: +65 dBm * Automotive Telematic Applications High Input P0.1 dB: +40 dBm Tx * Mobile Radio Positive Control: 0/+5V to 0/+8V TE Ultra Small Package: SOT26 Functional Diagram General Description The HMC446 & HMC446E are low-cost SPDT switches in 6-lead SOT26 packages for use in transmitreceive applications which require very low distortion at high signal power levels, up to 10 watts. The device can control signals from 824 - 894 MHz* and is especially suited for cellular booster and automotive telematic applications. The design provides exceptional P0.1 dB of +40 dBm and +65 dBm IIP3 on the Transmit (Tx) port. The Tx port is a reflective open when "Off" while the Rx port is a reflective short when "Off". On-chip circuitry allows single positive supply operation at very low DC current with a single control input (Vctl).
