SKY66189-11 Linear PA Block Diagram High linearity: +23 dBm with -50 dBc ACLR 85 C (WCDMA Test Model 1 with 64 DPCH) Description RF input and output internally matched to 50 ohms The SKY66189-11 is a high-linearity power amplifier (PA) with Excellent output return loss: < -20 dB fully matched input/output and high gain. The compact 5 x 5 mm Integrated active bias: performance compensated over temp PA is designed for FDD 3G/4G LTE small cell base stations operating from 1930 to 1995 MHz. The active biasing circuitry is PA On/Off function: 3.5 us switching time integrated to compensate PA performance over temperature, Integrated coupler for output power monitoring voltage, and process variation as well as an internal coupler for Single supply voltage: 3.3 V power monitoring. Pin-to-pin compatible PA family supporting all 3GPP bands The SKY66189-11 requires minimal external components and is part of a high-linearity, pin-to-pin compatible PA family Small 5 x 5 mm, 28-pin package supporting all 3GPP bands. (MSL3, 260 C per JEDEC J-STD-020) A block diagram of the SKY66189-11 is shown in Figure 1. The device package and pinout for the 28-pin device are shown in TM Skyworks Green products are compliant with Figure 2.
