SKY65364-21 Functional Block Diagram PA bypass mode LNA low-current mode with external resistor Description LNA bypass mode The Skyworks SKY65364-21 is a high-performance, Integrated control logic transmit/receive (T/R) front-end module (FEM). The device Internal RF match and bias circuits provides a complete T/R chain with T/R switches. All RF ports internally DC blocked The device transmit chain features +30 dBm output power and a Shutdown mode 40 percent power-added efficiency (PAE). Small footprint, MCM (28-pin, 6 x 6 mm) package The device receive chain features a low-noise amplifier (LNA) with (MSL3, 260 C per JEDEC J-STD-020) a 1.5 dB noise figure (NF) and 15 dB gain. The cascaded NF and gain, taking into account the 0.5 dB insertion loss TM Skyworks Green products are compliant with transmit/receive antenna switch, are 2.1 dB and 14.5 dB, all applicable legislation and are halogen-free. respectively, which makes the SKY65364-21 ideal for medium For additional information, refer to Skyworks power microwave links such as 900 MHz Industrial, Scientific, TM Denition of Green , document number and Medical (ISM) band applications. SQ040074. The module also has a shutdown mode, PA bypass mode, and LNA bypass mode to minimize power consumption. The device is mounted in a 28-pin, 6 x 6 mm Multi-Chip Module (MCM) surface-mount technology (SMT) package, which allows for a highly manufacturable low-cost solution. A functional block diagram of the SKY65364-21 is shown in Figure 1. The device package and pinout for the 28-pin MCM are shown in Figure 2.
