Figure 9. Transmit O Power.
Results
ACPM-7886 delivers good performance for TD-SCDMA
in the 2010 – 2025MHz frequency band see gures 10,
11, and 12. At Vdd of 3.5V, Vdd2 of 2.85 and Vcntl of 2V
and Pout of 28dBm this device produces eciency of
40% and ACLR1/ACLR2 of 41dBc and 56 dBc respectively.
In normal CDMA or WCDMA systems, receiver sensitiv-
ity is greatly aected by the TX power leakage, thus
the transmit o power is of great importance. Figure
9 shows transmit o power of -83dBm which results in
107dBc of dynamic range.
