Overview

Very Low Insertion Loss: 0.2 dB @ 1 GHz
High Input P1dB: +39 dBm
High Input IP3: +60 dBm

Positive Control: 0/+3V to 0/+5V
Compact SOT26 SMT Package

The HMC544A & HMC544AE are low cost SPDT switches in 6-lead SOT26 packages for use in transmitreceive applications which require very low insertion loss at medium power levels. These devices can control signals from DC to 4.0 GHz and are especially suited for 450, 900, 1900, 2300, and 2700 MHz applications with <0.5 dB insertion loss. This GaAs PHEMT design provides exceptional linearity performance of +36 dBm 1dB compression point and +60 dBm third order intercept at +3 volt bias. RF1 and RF2 are reflective opens when “Off”. On-chip circuitry allows positive control operation at very low DC current.
