4.9-5.8 GHz High-Linearity Power Amplifier SST11CP15 Data Sheet FEATURES: Small Package Size APPLICATIONS: High Linear Output Power: WLAN (IEEE 802.11a/n) 802.11a OFDM Spectrum mask compliance up Japan WLAN to 23 dBm Added EVM~2.5% up to 18 dBm, typically, HyperLAN2 across 5.1-5.8 GHz for 54 Mbps 802.11a signal Multimedia High Power-added Efficiency/Low Operating Current for 54 Mbps 802.11a Applications ~11% P = 19 dBm for 54 Mbps OUT Gain: Typically 26 dB gain across broadband 4.9-5.8 GHz Low Idle Current ~120 mA I CQ High Speed Power-up/-down Turn on/off time (10%~90%) <100 ns Low Shut-down Current (<1 A) On-chip Power Detection 20 dB Dynamic Range On-chip Power Detection 50 On-chip Input Matching and Simple Output Matching Packages Available 12-contact UQFN (2mm x 2mm x 0.6mm max thickness) PRODUCT DESCRIPTION The SST11CP15 is a high-linearity power amplifier that has The power amplifier IC also features easy board-level low power consumption and is based on the highly-reliable usage along with high-speed power-up/down control. Low InGaP/GaAs HBT technology. reference current (total I <5 mA) makes the REF SST11CP15 controllable by an on/off switching signal The SST11CP15 can be easily configured for high-linearity, directly from the baseband chip. These features coupled high-efficiency applications with superb power-added effi- with low operating current make the SST11CP15 ideal for ciency while operating over the entire 802.11a frequency the final stage power amplification in battery-powered band for U.S., European, and Japanese markets (4.9-5.8 802.11a WLAN transmitter and access point applications. GHz). The SST11CP15 is offered in 12-contact UQFN package The SST11CP15 has excellent linearity, typically ~2.5% with 0.6 mm maximum thickness. See Figure 2 for pin added EVM at 18 dBm output power which is essential for assignments and Table 1 for pin descriptions. 54 Mbps 802.11a operation while meeting 802.11a spec- trum mask at 23 dBm. SST11CP15 also has wide-range, single-ended power detectors which lower users cost on power control. 2011 Silicon Storage Technology, Inc.
