Hi all,
My customer evaluated the TRF370315 error vector magnitude with 2.45GHz fLO,
and they think the error is big.
Could you advice about the test result?
Conditions;
=========
1. fLO=(2.45GHz),+2dBm using a signal generator
2. I and Q voltage;
0.2V differential (DC), Vcom = 1.5V
(1) In:1.4 V , Ip:1.6V Qn:1.4 V, Qp:1.6 V
(2) In:1.4 V , Ip:1.6V Qn:1.6 V, Qp:1.4 V
(3) In:1.6 V , Ip:1.4V Qn:1.6 V, Qp:1.4 V
(4) In:1.6 V , Ip:1.4V Qn:1.4 V, Qp:1.6 V
Results;
=======
(1) +4.30 dBm
(2) +4.92 dBm
(3) +4.31 dBm
(4) +4.83 dBm
Note: Using spectrum analyzer for this measurement and
there are some spurious signals at 3.262GHz (-26dBm) and 1.639GHz (-32dBm) in any cases.
Regards,
Toshi
