DCS 1800 Mode
Perform the following steps to evaluate the
MAX2566/MAX2572 in the DCS 1800 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 DCS 1800 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 1510MHz at -10dBm to the
LOH port.
5) Connect GSM (J33) to the spectrum analyzer.
Configure the spectrum analyzer to measure spec-
tral mask for the GSM signal. Set the center fre-
quency to 1800MHz with 50MHz span and a
+10dBm reference level.
GSM 1900 Mode
Perform the following steps to evaluate the
MAX2566/MAX2572 in the GSM 1900 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 1900 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 1610MHz at -10dBm to the
LOH port.
5) Connect GSM (J33) to the spectrum analyzer.
Configure the spectrum analyzer to measure spec-
tral mask for the GSM signal. Set the center fre-
quency to 1900MHz with a +10dBm reference level.
Layout Considerations
The MAX2560/MAX2566/MAX2572 EV kits can serve as
guides for board layout. Keep PC board trace lengths
as short as possible to minimize parasitics. Also, keep
decoupling capacitors as close to the IC as possible
with a direct connection to the ground plane.
INTF2300 SPI Interface Board
The INTF2300 interface board is used to interface 3-
wire SPI protocol from a PC’s parallel port to the EV kit.
This board level translates 5V logic from the PC to VCC
of the EV kit (typically, this is 2.85V logic). The INTF2300
also provides buffering and EMI filtering. Its absolute
maximum supply voltage is 4.6V, limited by the break-
down of the buffer IC. The recommended operating
supply voltage range is +2.7V to +3.6V.
