HMC646LP2 646LP2E / v02.1009 GaAs MMIC 40W FAILSAFE SWITCH, 0.1 - 2.1 GHz Typical Applications Features The HMC646LP2(E) is ideal for: High Input P0.1dB: +46 dBm Tx • LNA Protection & T/R Switching Low Insertion Loss: 0.4 dB • TD-SCDMA / 3G Infrastructure High IIP3: +74 dBm • Satellite Subscriber Terminals Single Positive Control: 0/+3V to 0/+8V • Private Mobile Radio & Public Safety Handsets Failsafe operation; Tx ‘On’ when unpowered • Automotive Telematics 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 trans- 11 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 T M MHz* and is ideal for TD-SCDMA / 3G repeaters, PMR, automotive telematics, and satellite subscriber S terminal applications. The design provides excep- - tional P0.1dB of +46 dBm and +74 dBm IIP3 on the T Transmit (Tx) port. The failsafe topology provides a D low loss path from Tx to RFC, when no DC power is P S available. - S Electrical Specifi cations, T = +25°C, Vdd= 5V, Vctl = 0/+5 Vdc, 50 Ohm System* E A H Parameter Min.
