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