The HFA3661 is a monolithic bipolar device for down conversion applications in the 2.0GHz to 2.7GHz range. Manufactured in the Intersil UHF1X process, the device consists of a low noise amplifier and down conversion mixer. An energy saving power enable control feature assures isolation between transmit and receive channels for TDMA and/or half duplex systems. The device is designed for a high Output IP3, while maintaining low current and 5.5V to 2.7V supply operation. It requires low drive levels from the local oscillator and is housed in a small outline 20 lead SSOP package ideally suited for PCMCIA card applications.
