Passive GaAs MMIC Mixers Deliver a Wide IF Bandwidth
Hittite Microwave Corporation announces its double balanced GaAs MESFET mixers for use in test and measurement systems, military radios, commercial sensors and transceiver infrastructure, including critical functions of fixed and mobile protocols such as WiMAX and VSAT applications. The HMC557LC4 passive double balanced mixer provides an LO to RF port isolation of 48 dB and an input IP3 of +22 dBm across the frequency range of 2.5 to 7 GHz. The HMC558LC4 is a passive double balanced mixer that provides an LO to RF port isolation of 45 dB and an input IP3 of +24 dBm across the frequency range of 5.5 to 14 GHz. This mixer ensures wide IF bandwidth of DC to 6 GHz, enabling its use in multiple locations within traditional transceiver architectures.
