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).
2. Features and benefits
Low current consumption Low cost Operation to 500 MHz Low radiated energy Low external parts count; suitable for crystal/ceramic filter Excellent sensitivity, gain, and noise figure
3. Applications
Cordless telephone Portable radio VHF transceivers RF data links Sonobuoys Communications receivers Broadband LANs HF and VHF frequency conversion Cellular radio mixer/oscillator
