WCDMA Mode
Perform the following steps to evaluate the MAX2566/
MAX2572 in the WCDMA mode:
1) Verify shunt JU24 is in the LOUMTS position.
2) With MAX2560/MAX2566/MAX2572 control software
active in the REG screen, use Tables 2 and 3 to set
the operating mode to WCDMA.
3) Connect the I and Q outputs of the arbitrary wave-
form generator to the I (J15) and Q (J16) ports. Set
the generator to WCDMA settings. Verify 300mV
peak baseband signal on Q+/Q- (JU2) and I+/I-
(JU1), or 600mV peak-to-peak differential.
4) The MAX2566 EV kit requires an external LO input.
Apply an external LO 1565MHz at -10dBm to the
LOH port.
5) Connect RFH0 (J1) to the spectrum analyzer.
Configure the spectrum analyzer to measure ACPR
for the uplink WCDMA. Set the center frequency to
1950MHz with 50MHz span and a +10dBm refer-
ence level.
6) Adjust the R1 (VGCRF) and R6 (VGCIF) (only adjust
VGCIF if VGS = 1) to obtain an output power of
+8dBm after accounting for cable and connector loss.
The ACPR in 3.84MHz bandwidth at ±5MHz offset
should be -49dBc, and the ACPR in 3.84MHz band-
width at ±10MHz offset should be -62dBc. Note that
C112–C115 are disconnected for this measurement.
GSM 900 Mode
Perform the following steps to evaluate the
MAX2566/MAX2572 in the GSM 900 mode:
1) Verify shunts JU23–JU26 and JU33 positions with
Table 4.
2) With MAX2560/MAX2566/MAX2572 control software
active in the REG screen, use Tables 2 and 3 to set
the operating mode to GSM 900 mode.
3) Connect the I and Q outputs of the arbitrary wave-
form generator to the I (J15) and Q (J16) ports. Set
the generator to GSM settings. Verify 300mV peak
baseband signal on Q+/Q- (JU2) and I+/I- (JU1), or
600mV peak-to-peak differential.
4) The MAX2566 EV kit requires an external LO input.
Apply an external LO 1190MHz at -10dBm to the
LOH port.
5) Connect GSM (J3) to the spectrum analyzer.
Configure the spectrum analyzer to measure spec-
tral mask for the GSM signal. Set the center fre-
quency to 900MHz with 50MHz span and a
+10dBm reference level.
