5.1-5.9 GHz High-Linearity Power Amplifier

SST11CP16

Data Sheet

Product Description

SST11CP16 is a high-linearity power amplifier with low power consumption and is based on the highly-

reliable InGaP/GaAs HBT technology. It can be easily configured for high-linearity, high-efficiency

applications, with superb power-added efficiency, while operating over the 802.11a frequency band for

U.S. and European markets (5.1-5.9 GHz).

SST11CP16 has excellent linearity, typically ~3% added EVM at 21.5 dBm output power for 54 Mbps

802.11a operation, at 5.0V, while meeting 802.11a spectrum mask at 25 dBm. SST11CP16 provides 19

dBm with less than 1.8% EVM, using 802.11ac modulation with 80 MHz bandwidth and 351 Mbps data rate.

This power amplifier also provides a wide dynamic-range, linear power detector that is temperature and

VSWR insensitive. This integrated power detector can lower the cost of power control.

The power amplifier IC also features easy board-level operation along with high-speed power-up/-

switching signal directly from the baseband chip. These features coupled with low operating current

make the SST11CP16 ideal for the final stage power amplification in 802.11a/n/ac WLAN transmitter

applications.

The SST11CP16 is offered in 16-contact XQFN package with 0.5 mm maximum thickness. See Figure

2 for pin assignments and Table 1 for pin descriptions.
