SST12LP15
Not Recommended for New Designs
The SST12LP15 is a high-power, high-gain power amplifier based on the highly-
reliable InGaP/GaAs HBT technology. Easily configured for high-power, high-effi-
ciency applications with superb power-added efficiency, it typically provides 35 dB
gain with 26% power added efficiency @ POUT = 24 dBm for 802.11g and 29%
power-added efficiency @ POUT = 25 dBm for 802.11b. The SST12LP15 has
excellent linearity while meeting 802.11g spectrum mask at 24+ dBm, and is
offered in 16-contact VQFN package.
Features
? High Gain:
– Typically 35 dB gain across 2.4~2.5 GHz over tempera-
ture 0°C to +80°C
? High linear output power:
– >29 dBm P1dB (Exceeding maximum rating of average
output power, never measure with CW source! Pulsed
single-tone source with <50% duty cycle is recom-
mended.)
– Meets 802.11g OFDM ACPR requirement up to 25 dBm
– Added EVM~4% up to 23.5 dBm for
54 Mbps 802.11g signal
– Meets 802.11b ACPR requirement up to 25 dBm
? High power-added efficiency/Low operating cur-
rent for both 802.11g/b applications
– ~26%/290 mA @ P OUT = 24 dBm for 802.11g
– ~29%/340 mA @ P OUT = 25 dBm for 802.11b
? Built-in Ultra-low I REF power-up/down control
– I REF <2 mA
? Low idle current
– ~50 mA I CQ
? High-speed power-up/down
– Turn on/off time (10%~90%) <100 ns
– Typical power-up/down delay with driver delay included
<200 ns
? High temperature stability
– ~1 dB gain/power variation between 0°C to +80°C
– ~1 dB detector variation over 0°C to +80°C
? Low shut-down current (< 0.1 μA)
? On-chip power detection
? 25 dB dynamic range on-chip power detection
? Simple input/output matching
? Packages available
– 16-contact VQFN (3mm x 3mm)
– Non-Pb (lead-free) packages available
Applications
? WLAN (IEEE 802.11g/b)
? Home RF
? Cordless phones
? 2.4 GHz ISM wireless equipment
