The HFA3624 Up/Down converter is a monolithic bipolar device for up/down conversion applications in the 2.4GHz to 2.5GHz range. Manufactured in the Intersil UHF1X process, the device consists of a low noise amplifier and down conversion mixer in the receive section and an up conversion mixer with power preamp in the transmit section. An energy saving power enable control feature assures isolation between the receive and transmit circuits for time division multiplexed systems. The device requires low drive levels from the local oscillator and is housed in a small outline 28 lead SSOP package ideally suited for PCMCIA card applications.
