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. • RF Frequency Range . . . . . . . . . . . . . . 2.0GHz to 2.7GHz • IF Operation . . . . . . . . . . . . . . . . . . . . 10MHz to 250MHz • High Conversion Gain 2.0GHz . . . . . . . . . . . . . . . . . 40dB 2.7GHz . . . . . . . . . . . . . . . . . 36dB • High Output IP3 . . . . . . . . . . . . . . . . . . . . . . . . . . . 11dBm • Single Supply Battery Operation . . . . . . . . . 2.7V to 5.5V • Power Enable Control • LNA Bypass Control Applications • Wireless Local Loop Systems Ordering Information PART NUMBER TEMP.
