Description
M/A-COM’s SA65-0003 is an integrated assembly contain-
ing a GaAs FET MMIC LNA and GaAs FET mixer. This
device is packaged in a 16-leaded QSOP plastic surface
mount package. The amplifier can be biased with either
+3V or +5V, the mixer requires no DC bias. The conversion
gain of the integrated combination is typically 6 dB at +3V
bias and 8 dB at +5V bias. The SA65-0003 is ideally
suited for RF/IF communications applications requiring
down conversion with some gain.
This MCM contains a mixer that is fabricated using a
mature 1-micron GaAs process, it also contains an LNA
that is fabricated using a low cost mature 0.5-micron gate
length GaAs MESFET process. Both die feature full
passivation for increased performance and reliability.

1. For IP3 measurements, RFIN = -24 dBm, this low RF IN level gets amplified through the LNA.
2. For IP3 measurements, RFIN2 = RFIN1 + 10 MHz, LO = RFIN1—140 MHz.
3. For IP3 measurements, IP3 = IMR/2 + PIN.
4. RF IN to IF Isolation is typically 0 dB.
5. Reverse Isolation is measured from IF to RFIN with the IF at –10 dBm, LO at +13 dBm.
6. The amplifier has a normal gain of 12.5 dB, 3V bias and 14.0 dB, 5V bias. Amplifier typical Noise Figure = 1.5 dB.

14. Pin 2 allows use of an external resistor to ground for op-
tional higher current. For 20 mA operation, no resistor is
used.
The spurious table shows the spurious signals resulting from
the mixing of the RFIN and LO input signals, assuming down
conversion. The number of dB below the conversion loss
level indicates the mixing products. The lower frequency
mixing term is shown for two different input levels. The top
number is for an RFIN power level of –19 dB; the lower
For IDD » 30 mA, R2 = 43 Ohms
For IDD » 45 mA, R2 = 15 Ohms
For IDD » 60 mA, R2 = 10 Ohms
number is for –29 dB.
Assuming the LNA gain is
approximately 14 dB, the mixer input will see approximately
–5 dB and –15 dB.
