Product data sheet
1. General description
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. It is available in an 8-lead SO (surface-mount miniature
package).
