EV2HMC994APM5

EV2HMC994APM5 is an evaluation board for GaAs, pHEMT, MMIC, power amplifier. It consists of a 2-layer PCB fabricated from 10mil thick, Rogers 4350B, copper clad, mounted to an aluminium heat spreader. The heat spreader assists in providing thermal relief to the device as well as mechanical support to the PCB. Mounting holes on the heat spreader allows it to be attached to a heat sink for improved thermal management. The RFIN and RFOUT ports are populated with 2.9mm, female coaxial connectors, and their respective RF traces have a 50 ohm characteristic impedance. The EV2HMC994APM5 contains an on-board, surface-mount bias tee circuit. This circuit allows the EV2HMC994APM5 to connect directly to RF test equipment. However, this on-board, surface-mount bias tee circuit limits the operating frequency to approximately 22GHz. This frequency contrasts with the DC to 28GHz operating frequency range that is achievable when the HMC994APM5E is operating with a broadband connectorized bias tee.
