HMC544E数据手册RF/IF射频/中频RFID的射频开关规格书PDF

描述 Description

General Description
The HMC544 & HMC544E are low cost SPDT switches in 6-lead SOT26 packages for use in transmit-receive 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 +36dBm 1dB compression point and +55 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.
