SKY66184-11 Linear PA Block Diagram (WCDMA Test Model 1 with 64 DPCH) RF input and output internally matched to 50 Description Excellent output return loss: < 17 dB SKY66184-11 is a high-linearity power amplifier (PA) with fully Integrated active bias: performance compensated over temp matched input/output and high gain. The compact 5 x 5 mm PA is designed for FDD 3G/4G LTE small cell base stations operating PA On/Off function: 2.5 s switching time from 2100 to 2200 MHz. The active biasing circuitry is integrated Integrated coupler for output power monitoring to compensate PA performance over temperature, voltage, and Single supply voltage: 3.3 V process variation as well as an internal coupler for power monitoring. Minimal external components The SKY66184-11 requires minimal external components and is Pin-to-pin compatible PA family supporting all 3GPP bands 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 SKY66184-11 is shown in Figure 1. The device package and pinout for the 28-pin device are shown in Figure 2. Table 1 lists the pin-to-pin compatible parts in the PA TM Skyworks Green products are compliant with family. all applicable legislation and are halogen-free.
