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.

NOTES:
4. 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.
