The HMC546LP2E is a failsafe SPDT switch in a leadless DFN surface-mount plastic package for use in transmit/receive and LNA protection applications that require very low distortion and high power handling of up to 10 watts.The HMC546LP2E requires external matching and is suitable for narrow-band applications within 200 MHz to 2700 MHz.This narrow-band switch is well suited for WiMAX and WiBro repeaters, private mobile radio (PMR), and automotive telematic applications. The design provides exceptional P0.1dB of 40 dBm and IIP3 of 65 dBm on the transmit (Tx) port. The failsafe topology allows the switch to provide a low loss path from RFC to Tx, when no dc power is available.ApplicationsLNA protection, WiMAX, and WiBroCellular, PCS, 3G, and TD-SCDMA infrastructurePrivate mobile radio and public safety handsetsAutomotive telematics

The HMC549MS8GE is a GaAs pHEMT MMIC Low Noise Amplifier that are ideal pre-amplifiers for CATV Set Top Box, Home Gateway, and Digital Television receiver operating between 40 and 960 MHz. This high dynamic range LNA has been optimized to provide 3.5 dB noise figure and +27 dBm output IP3 from a single supply of +5V @ 120 mA. The outputs of this LNA are extremely well balanced, and can be used to drive a differential input tuner with very high input IP2 requirements. This dual purpose LNA can also be used as an active splitter driving two single-ended input tuners. This LNA is housed in a RoHS compliant MSOP8G SMT package with exposed ground paddle.ApplicationsDTV ReceiversMulti-Tuner Set Top BoxesPVRs & Home Gateways

The HMC550 and HMC550E are low-cost SPST Failsafe switches in 6-lead SOT26 plastic packages for use in switching applications which require low insertion loss and very low current consumption. With 0.7 dB typical loss, these devices can control signals from DC to 6.0 GHz and are especially suited for IF and RF applications including RFID, ISM, automotive and battery powered tags and portables. RF1 and RF2 are reflective opens when "Off". The switch requires a minimal amount of DC current in the "On" state, and offers compatibility with CMOS and some TTL logic families. The failsafe topology results in the switch being normally "On", i.e. low insertion loss from RF1 to RF2, when no DC bias is applied.ApplicationsRFID & Electronic Toll Collection (ETC)Tags, Handsets & PortablesISM, WLAN, WiMAX & WiBroAutomotive TelematicsTest Equipment

The HMC553 devices are passive (HMC553) and general purpose (HMC553LC3B) double-balanced mixers that are available in a chip (HMC553) and a leadless RoHS compliant SMT package (HMC553LC3B), both of which can be used as an upconverter or downconverter between 7 GHz and 14 GHz. These mixers are fabricated in a GaAs metal semiconductor field effect transistor (MESFET) process, and require no external components or matching circuitry. The HMC553 devices provide excellent LO to RF and LO to IF isolation due to optimized balun structures and operates with LO drive levels as low as 9 dBm. Measurements were made with the HMC553 chip mounted into in a 50 Ω test fixture and includes the parasitic effects of wire bond assembly. Connections were made with a 1 mil wire bond with minimal length (<12 mil). The RoHS compliant HMC553LC3B eliminates the need for wire bonding, and is compatible with high volume surface mount manufacturing techniques.ApplicationsPoint-to-point radiosPoint-to-multipoint radiosTest equipment and sensorsMilitary end useMicrowave radioSpaceCommunications, radar, and electronic warfare (EW)
