DATA SHEET SKY65174-21: 2.4 to 2.5 GHz WLAN Power Amplifier Module Applications Description The SKY65174-21 is a highly integrated power amplifier module IEEE 802.11 b/g/n WLAN systems (PAM) intended for high performance wireless local area network ISM band transmitters (WLAN) requiring up to +27 dBm linear output power. Wireless access points, routers, gateways The SKY65174-21 is fabricated using Skyworks high reliability Heterojunction Bipolar Transistor (HBT) InGaP process, which allows for single supply operation while maintaining high Features efficiency and good linearity. PA linear output power: +27 dBm <2.5% EVM The PAM is packaged in a 10-pin, 4 x 4 mm Multi-Chip Module High gain: 35 dB (MCM) together with power detector, biasing, and input/output matching components. This architecture makes the SKY65174-21 Input/Output internally matched to 50 a highly integrated solution requiring a minimum number of Internal, active bias circuits external components. MCM (10-pin, 4 x 4 mm) package A functional block diagram of the SKY65174-21 is shown in (MSL3, 260 C per JEDEC J-STD-020) Figure 1. The 10-pin MCM package and pinout are provided in Figure 2. Signal pin assignments and functional pin descriptions TM Skyworks Green products are compliant with are provided in Table 1. all applicable legislation and are halogen-free.
