HFA3664
2.7GHz UpConverter with Gain Control
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.
