DESCRIPTION

The SA612A is a low-power VHF monolithic double-balanced mixer

with on-board oscillator and voltage regulator. It is intended for low

cost, low power communication systems with signal frequencies to

500MHz and local oscillator frequencies as high as 200MHz. The

mixer is a “Gilbert cell” multiplier configuration which provides gain

of 14dB or more at 45MHz.

The oscillator can be configured for a crystal, a tuned tank

operation, or as a buffer for an external L.O. Noise figure at 45MHz

is typically below 6dB and makes the device well suited for high

performance cordless phone/cellular radio. The low power

consumption makes the SA612A excellent for battery operated

equipment. Networking and other communications products can

benefit from very low radiated energy levels within systems. The

SA612A is available in an 8-lead dual in-line plastic package and an

8-lead SO (surface mounted miniature package).
