Features - High linearity: OIP3 > +48 d Bm - OP1d B = +33.5 d Bm - ACLR = - 45 d Bc for POUT = +25.4 d Bm - High efficiency: PAE = 42% - High gain = 24.6 d B - Internal RF match and bias circuits - Single DC supply: 5 V - Small footprint, MCM (20-pin, 6 x 6 mm) SMT package (MSL3, 260 °C per JEDEC J-STD-020) Figure 1. SKY65120-21 Block Diagram Description Skyworks SKY65120-21 is a fully-matched, surface mount Power Amplifier (PA) designed for WCDMA, PCS, DCS, UTMS, and TDSCDMA radio, repeaters, transmitters, and WCS fixed wireless units operating in the 2110 to 2170 MHz bandwidth. All active circuitry in the module is contained in a single Ga As Microwave Monolithic Integrated Circuit (MMIC). The device is manufactured using Skyworks Al Ga As Heterojunction Bipolar Transistor (HBT) process, which allows for single supply operation while maintaining high efficiency and good linearity. A block diagram of the SKY65120-21 is shown in Figure 1. The device package and pinout for the 20-pin MCM are shown in Figure 2. Figure 2.
