SA602A
Double-balanced mixer and oscillator
Rev. 3 — 27 May 2014
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).
2. Features and benefits
Low current consumption: 2.4 mA typical
Excellent noise figure: <4.7 dB typical at 45 MHz
High operating frequency
Excellent gain, intercept and sensitivity
Low external parts count; suitable for crystal/ceramic filters
SA602A meets cellular radio specifications
3. Applications
Cellular radio mixer/oscillator
Portable radio
VHF transceivers
RF data links
HF/VHF frequency conversion
Instrumentation frequency conversion
Broadband LANs

The mixer outputs (OUT_A and OUT_B pins) are also internally biased. Each output is
connected to the internal positive supply by a 1.5 k resistor. This permits direct output
termination yet allows for balanced output as well. Figure 5 shows three single-ended
output configurations and a balanced output.
