Figure 21. Harmonic Suppresion Table
Notes:
12. The harmonic suppression table shows the spurious signals present due to the mixing of the RF and LO at down conversion mode.
13. Test conditions
a. RF = 1.91GHz @ -10dBm
b. LO = 1.7GHz @ 0 dBm
c. RF and LO Intermodulation Harmonics are referenced to the signal level produced by the down converted IF signal at 210MHz at the IF
amplifier output
d. LO Harmonics are referenced to the signal level of the LO signal at 1.7GHz at the IF amplifier output.

Description
IF Amplifier inputs. This is the signal output from the Mixer/IF Ampli-
fier interstage match. (See product application note)
RF differential signal input. Simple matching is required for good RF
return loss. (See product application note)
Signal at mixer output.This signal will be fed into the Mixer/IF Ampli-
fier interstage match. (See product application note)
Ground connection. For normal operation, all electrical grounds
must be connected together.
DC Power supply for the mixer circuit.
50 Ohm Local oscillator input. The local oscillator can be driven
differential or single ended.
No contact.
200 Ohm differential amplifier output. A 4:1 balun is required to con-
vert the differential output to single ended. (See product application
note)
DC Power supply for the IF amplifier circuit.
