HFA3664 TM Data Sheet April 1999 File Number 4242.3 2.7GHz UpConverter with Gain Control Features The HFA3664 UpConverter with Gain Control is a monolithic bipolar PRISM® device for up conversion applications in the 2.3GHz to 2.7GHz range. Manufactured in the Intersil UHF1X process, the device consists of a double balanced mixer followed by a variable gain power preamp. An energy saving, TTL Compatible, power enable input provides on/off bias current control to the mixer and amplifier. The device 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 . . . . . . . . . . . . . . 2.3GHz to 2.7GHz • IF Operation . . . . . . . . . . . . . . . . . . . . . 10MHz to 400MHz • Gain Control Range . . . . . . . . . . . . . . . . . . . . . . . . . .20dB • Single Supply Operation. . . . . . . . . . . . . . . . . 2.7V to 5.5V • High Output 1dB Compression. . . . . . . . . . . . . . . . . 6dBm • High Power Gain . . . . . . . . . . . . . . . . . . . . . . . . . . . .18dB • Power Enable/Disable Control Applications • Wireless Local Loop Systems Ordering Information PART NUMBER • PCMCIA Wireless Transceiver TEMP.

Required external resistor for Mixer biasing. Value optimized for 2.7mA bias current with R = (VCC - 0.93) /2.7mA. Most Mixer cell characteristics like Gain, NF etc., can be affected when biasing is outside the optimum value. 5. The combination of these attenuator pads and the Band Pass Filter insertion loss shall bring the overall Cascaded Gain at the desired frequency of operation from 21dB to 22dB for best performance. The selection of these values is optional. The total gain, LO feedthru, Mixer and Preamplifier interaction (stability) and output compression point performances can be manipulated according to the user needs. 4-5
