General Description  
Functional Diagram  
The HMC646LP2(E) is an SPDT switch in a leadless  
DFN surface mount plastic package for use in trans-  
mit / 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 excep-  
tional P0.1 dB 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.
