SA612A is a low power VHF monolithic double-balanced mixer with on-board oscillator and voltage regulator, intended for low cost, low power communication systems with signal frequencies to 500MHz and local oscillator frequencies as high as 200MHz.
The Philips SA612A is a low-power VHF monolithic double-balanced mixer featuring an on-board oscillator and voltage regulator. It utilizes a Gilbert cell multiplier configuration to provide gain of 14dB or more at 45MHz, making it suitable for cost-effective, low-power communication systems operating up to 500MHz.
The device is designed for applications such as cordless telephones, cellular radios, VHF transceivers, and broadband LANs. It supports operation to 500MHz with local oscillator frequencies up to 200MHz and is available in 8-lead plastic dual in-line (DIP) and surface-mount (SO) packages.
