SKY85803 Block Diagram Small LGA (24-pin, 4 x 4 mm) package (MSL3, 250 C per JEDEC J-STD-020) Designed for ease of use, all RF ports are matched to 50 to simplify PCB layout and the interface to the transceiver. The device also includes a transmitter power detector with 20 dB of dynamic range for each transmit chain. Each PA has a separate digital enable control for transmitter on/off control. The power ramp rise/fall time is < 0.4 s. The SKY85803 also provides a notch filter from 3.260 to 3.267 GHz and 3.28 to 3.89 GHz before the input of each 2.4 GHz and 5.0 GHz PA, respectively. Description The SKY85803 is manufactured in a compact, 4 x 4 mm, 24-pin The SKY85803 is a complete 802.11a/b/g/n/ac WLAN RF Front- Land Grid Array (LGA) package. End Module (FEM) that provides all the functionality of the Power Amplifiers (PAs), filtering, power detector, transmit/receive (T/R) A functional block diagram is shown in Figure 1. The pin switch, diplexers, and associated matching. configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in The device provides a complete 2.4 GHz and 5.0 GHz WLAN RF Table 1. solution from the output of the transceiver to the antenna in an ultra-compact form factor. The SKY85803 delivers < 2% EVM at rated AC power, which meets the stringent linearity conditions of the 802.11ac standard. Skyworks Solutions, Inc.
