SA612A
Double-balanced mixer and oscillator
Rev. 3 — 4 June 2014
Product data sheet
1. General 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 500 MHz and local oscillator frequencies as high as
200 MHz. The mixer is a ‘Gilbert cell’ multiplier configuration that provides gain of 14 dB or
more at 45 MHz.
The oscillator can be configured for a crystal, a tuned tank operation, or as a buffer for an
external LO. Noise figure at 45 MHz is typically below 6 dB 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 SO (surface-mounted miniature
package).
