Description

The SA602A is a low-power VHF monolithic double-balanced mixer with input amplifier,
on-board oscillator, and voltageregulator. 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 isa ‘Gilbert cell’ multiplier
configuration which typically provides 18 dB ofgain at 45 MHz. The oscillator operates to
200 MHz. It can be configured as a crystal oscillator, a tuned tankoscillator, or a buffer for
an external LO. For higher frequencies, the LOinput 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 inan 8-lead SO (surface-mount miniature
package).
