PRODUCT DESCRIPTION
The SST12LP10 is a high-performance power amplifier based on the highly-reliable InGaP/GaAs HBT technology.
The SST12LP10 can be easily configured for high-power, high-efficiency applications with superb power-added efficiency while operating over the 2.4~2.5 GHz frequency band. It provides over 26 dB gain with 19% power-added efficiency @ POUT = 20 dBm for 802.11g and 30% poweradded efficiency @ POUT = 24 dBm for 802.11b.
The SST12LP10 has excellent linearity (over 20 dBm linear output with total system EVM<5%) which is essential for 54 Mbps 802.11g operation.
The power amplifier IC also features easy board-level usage along with high-speed power-up/down control and ultra-low reference current (~3 mA). These features coupled with low operating current make the SST12LP10 ideal for the final stage power amplification in battery-powered 802.11g/b WLAN transmitter applications.
The SST12LP10 is offered in 16-contact VQFN package. See Figure 1 for pin assignments and Table 1 for pin descriptions.

General Description
The MAX19999 dual-channel downconverter provides 8.3dB of conversion gain, +24dBm input IP3, +11.4dBm 1dB input compression point, and a noise figure of 10.5dB for 3000MHz to 4000MHz WiMAX™ and LTE diversity receiver applications. With an optimized LO frequency
range of 2650MHz to 3700MHz, this mixer is ideal for low-side LO injection architectures.
In addition to offering excellent linearity and noise performance, the MAX19999 also yields a high level of component integration. This device includes two double-balanced passive mixer cores, two LO buffers, and a pair of differential IF output amplifiers. Integrated onchip baluns allow for single-ended RF and LO inputs.
The MAX19999 requires a nominal LO drive of 0dBm and a typical supply current of 388mA at VCC = +5.0V or 279mA at VCC = +3.3V.
The MAX19999 is pin compatible with the MAX19997A 1800MHz to 2900MHz mixer and pin similar with the MAX19985/MAX19985A and MAX19995/MAX19995A series of 700MHz to 2200MHz mixers, making this entire family of downconverters ideal for applications where a common PCB layout is used across multiple frequency bands.
The MAX19999 is available in a compact 6mm x 6mm, 36-pin thin QFN package with an exposed pad. Electrical performance is guaranteed over the extended temperature range, from TC = -40°C to +85°C.
