Double-Balanced Mixer and Oscillator

The SA602A is a low-power VHF monolithic double-balanced mixer with input amplifier, on-board oscillator, and voltage regulator. It is intended for high-performance, low-power communication systems. The guaranteed parameters of the SA602A make this device well-suited for cellular radio applications. The mixer is a "Gilbert cell" multiplier configuration which typically provides 18 dB of gain at 45 MHz. The oscillator operates to 200 MHz. It can be configured as a crystal oscillator, a tuned tank oscillator, or a buffer for an external LO. For higher frequencies, the LO input may be externally driven. The noise figure at 45 MHz is typically less than 5 dB. The gain, intercept performance, low-power and noise characteristics make the SA602A a superior choice for high-performance battery operated equipment.
