SKY66181-11 Linear PA Block Diagram (WCDMA Test Model 1 with 64 DPCH) RF Input and Output internally matched to 50 Description Excellent output return loss: < 30 dB The SKY66181-11 is a high-linearity power amplifier (PA) with Integrated active bias: performance compensated over temp fully matched input/output and high gain. The compact 5 x 5 mm PA On/Off function: < 2 s switching time PA is designed for FDD 3G/4G LTE small cell base stations Integrated coupler for output power monitoring operating from 1805 to 1880 MHz. The active biasing circuitry is integrated to compensate PA performance over temperature, Single supply voltage: 3.3 V voltage, and process variation as well as an internal coupler for Minimal external components power monitoring. Pin-to-pin compatible PA family supporting all 3GPP bands The SKY66181-11 requires minimal external components and is Small 5 x 5 mm, 28-pin package part of a high-linearity, pin-to-pin compatible PA family (MSL3, 260 C per JEDEC J-STD-020) supporting all 3GPP bands. A block diagram of the SKY66181-11 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. Table 1 lists the pin-to-pin compatible parts in the PA all applicable legislation and are halogen-free. family.
