Philips Semiconductors
Double-balanced mixer and oscillator
Product specification
NE/SA612A
DESCRIPTION
The NE/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 NE/SA612A excellent for battery operated
equipment. Networking and other communications products can
benefit from very low radiated energy levels within systems. The
NE/SA612A is available in an 8-lead dual in-line plastic package and
an 8-lead SO (surface mounted miniature package).
