Pin Name Description
1, 12 IFA_IN+ / IFA_IN- IF Amplier inputs. This is the signal output from the Mixer/IF Ampli-
er interstage match. (See product application note)
2, 11 RF+ / RF- RF dierential signal input. Simple matching is required for good RF
return loss. (See product application note)
3, 10 MIX_OUT+ / MIX_OUT- Signal at mixer output.This signal will be fed into the Mixer/IF Ampli-
er interstage match. (See product application note)
4,9, 15 GND Ground connection. For normal operation, all electrical grounds
must be connected together.
5 VDD1 DC Power supply for the mixer circuit.
6, 7 LO+ / LO - 50 Ohm Local oscillator input. The local oscillator can be driven
dierential or single ended.
8 NC No contact.
13, 16 IF + / IF- 200 Ohm dierential amplier output. A 4:1 balun is required to con-
vert the dierential output to single ended. (See product application
note)
14 VDD2 DC Power supply for the IF amplier circuit.
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
amplier output
d. LO Harmonics are referenced to the signal level of the LO signal at 1.7GHz at the IF amplier output.
