HPMX-7201 Recommended Operating Conditions
Vcc = 2.7 to 3.6V, VccBat = 2.7 to 4.2V.
T
ambient
= -40C to 85C.
IF Frequency (both bands) 130 MHz typically.
Typical cdmaMixOut Frequency: 1850 to 1910 MHz.
PCS Local Oscillator Frequency: 1720 to 1780 MHz for low side LO, which is often used to allow a single LO
for transmit and receive operation, but is not required by the HPMX-7201.
Cellular Band RF Output Frequency: 824 to 849 MHz.
Cellular Band Local Oscillator Frequency: 954 to 979 MHz.*

High side
LO is required as the Cellular band upconverter features image rejection.
HPMX-7201 Standard Test Conditions
Unless otherwise noted, all test data was taken on packaged parts under the following conditions. The test
circuit is shown in Figure 31 (demo schematic) and in Figure 32 (IF balun).
RF powers are into 50
unless specified otherwise.
Vcc= 3.0V, VccBat = 3.6V, T

IF input frequency at ifInP and ifInM: 130 MHz. IF differential input voltage 480 mVp-p across a matched
360
differential impedance (240 mVp-p at ifInP and ifInM, with a single ended impedance of 180
).
This input level is calculated from a 50
power source delivering -11 dBm to a lossy 7.2:1 impedance
transforming network. The test circuit for this input is shown in Figure 32.
PCS CDMA LO input at LoIn: 1750 MHz at –11dBm single ended.
PCS CDMA RF frequency at cdmaMixOut, cdmaDrvIn, cdmaDrvOut1, and cdmaDrvOut2: 1880 MHz,
matched to 50
.
Cellular AMPS LO input at LoIn: 965 MHz, -11 dBm.
Cellular RF frequency at ampsMixOut, ampsDrvIn, ampsDrvOut: 835 MHz, matched to 50
.
