Features

Low insertion Loss: 0.4 dB high isolation: 35 dB Fast Switching Speed: 2 ns high input iP3: +50 dBm Typical Applications the hMc239AS8 / hMc239AS8e is ideal for:

  • MMDS & WirelessLAN
  • Basestation Infrastructure
  • Portable Wireless General Description The HMC239AS8 & HMC239AS8E are low-cost GaAs MMic SPDt switches in 8-lead SO ic packages. the switch can control signals from D c to 2.5 G hz. it is especially suited for low or medium power applica - tions which require extremely fast switching with minimal insertion loss. the two control voltages require a minimal amount of D c current which is opti - mal for battery powered radio systems. RF1 and RF2 are reflective shorts when “Off”.

Typical Application Circuit Evaluation Circuit Board The circuit board used in the application should be generated with proper RF circuit design techniques. Signal lines at the RF port should have 50 Ohm impedance and the package ground leads and package bottom should be connected directly to the ground plane similar to that shown above. The eval- uation circuit board shown above is available from hittite Microwave corporation upon request. item Description J1 - J3 PcB Mount SMA RF c onnector J4 - J6 Dc Pin c1 - c3 330 pF capacitor, 0402 Pkg.
