DATA SHEET SKY66001-11: 2100 to 2200 MHz, +19 dBm Linear Power Amplifier Applications Description • Residential femtocells The SKY66001-11 linear Power Amplifier (PA) is a fully matched surface mount module developed for WCDMA applications operating from 2100 to 2200 MHz. The device meets the stringent spectral linearity requirements of WCDMA femtocell applications with high power-added efficiency. An integrated directional coupler eliminates the need for any external coupler. • WCDMA, Band I • Small cells Features • Small signal gain: 28.6 dB • ACLR at POUT = +19 dBm: –51 dBc • PA on/off control • I/O impedance internally matched to 50 Ω • Single DC supply: 3.3 V to 4.6 V • Minimal number of external components required • Small footprint MCM (10-pin, 3 x 3 mm) package (MSL3, 260 °C per JEDEC J-STD-020) The GaAs MMIC contains all active amplifier circuitry, which includes input and interstage matching circuits. An output match into a 50 Ω load, realized off-chip within the module package, optimizes efficiency and power performance. The SKY66001-11 is manufactured with Skyworks InGaP GaAs HBT process, which provides for all positive voltage DC supply operation and maintains high efficiency and good linearity. The primary bias to the device can be supplied directly from any suitable power supply with an output of 4.2 V. Power down is achieved by setting the VEN pin to 0 V. No external supply side switch is needed since typical “off” leakage is a few microamps with full primary voltage supplied from the main power supply. The SKY66001-11 is packaged in a 10-pin, 3 x 3 mm Multi-Chip Module (MCM), which allows for a highly manufacturable low-cost solution. The 10-pin MCM package and pinout are shown in Figure 1. A functional block diagram of the SKY66001-11 is shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1. Figure 1.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. Note 2: Case operating temperature (Tc) refers to the temperature of the bottom ground pad. CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
