DATA SHEET SKY66001-11: 2100 to 2200 MHz, +19 dBm Linear Power Amplifier Applications Description The SKY66001-11 linear Power Amplifier (PA) is a fully matched Residential femtocells surface mount module developed for WCDMA applications WCDMA, Band I operating from 2100 to 2200 MHz. The device meets the stringent Small cells spectral linearity requirements of WCDMA femtocell applications with high power-added efficiency. An integrated directional coupler eliminates the need for any external coupler. Features The GaAs MMIC contains all active amplifier circuitry, which Small signal gain: 28.6 dB includes input and interstage matching circuits. An output match into a 50 load, realized off-chip within the module package, ACLR at POUT = +19 dBm: 51 dBc optimizes efficiency and power performance. PA on/off control The SKY66001-11 is manufactured with Skyworks InGaP GaAs I/O impedance internally matched to 50 HBT process, which provides for all positive voltage DC supply Single DC supply: 3.3 V to 4.6 V operation and maintains high efficiency and good linearity. The primary bias to the device can be supplied directly from any Minimal number of external components required suitable power supply with an output of 4.2 V. Power down is Small footprint MCM (10-pin, 3 x 3 mm) package achieved by setting the VEN pin to 0 V. No external supply side (MSL3, 260 C per JEDEC J-STD-020) switch is needed since typical off leakage is a few microamps with full primary voltage supplied from the main power supply. Skyworks Green products are compliant with The SKY66001-11 is packaged in a 10-pin, 3 x 3 mm Multi-Chip all applicable legislation and are halogen-free. Module (MCM), which allows for a highly manufacturable low-cost For additional information, refer to Skyworks solution.
