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.
