Product specification
SA612A
Double-balanced mixer and oscillator

1997 Nov 07
853-0391 18662
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).
