HMC646LP2 / 646LP2E
v02.1009
GaAs MMIC 40W FAILSAFE SWITCH, 0.1 - 2.1 GHz
Typical Applications
The HMC646LP2(E) is ideal for: • LNA Protection & T/R Switching • TD-SCDMA / 3G Infrastructure • Satellite Subscriber Terminals • Private Mobile Radio & Public Safety Handsets • Automotive Telematics
Features
High Input P0.1dB: +46 dBm Tx Low Insertion Loss: 0.4 dB High IIP3: +74 dBm Single Positive Control: 0/+3V to 0/+8V Failsafe operation; Tx ‘On’ when unpowered 2x2mm DFN SMT Package
Functional Diagram
General Description
The HMC646LP2(E) is an SPDT switch in a leadless DFN surface mount plastic package for use in transmit / receive and LNA protection applications which require very low distortion and high power handling of up to 40 watts with less than 10% duty cycle. This robust switch can control signals from 100 - 2100 MHz* and is ideal for TD-SCDMA / 3G repeaters, PMR, automotive telematics, and satellite subscriber terminal applications. The design provides exceptional P0.1dB of +46 dBm and +74 dBm IIP3 on the Transmit (Tx) port. The failsafe topology provides a low loss path from Tx to RFC, when no DC power is available.
