DATA SHEET SKY65364-11: 900 MHz Transmit/Receive Front-End Module Applications • Automated meter reading • Advanced metering infrastructure • ISM systems Description Skyworks SKY65364-11 is a high performance, transmit/receive (T/R) Front-End Module (FEM). The device provides a complete T/R chain with T/R switches. The device transmit chain features +30.5 dBm output power and a 40 percent Power Added Efficiency (PAE). The device receive chain features a Low Noise Amplifier (LNA) with a 1.7 dB Noise Figure (NF) and 16.0 dB gain. The cascaded NF and gain, taking into account the 0.5 dB insertion loss transmit/receive antenna switch, are 2.2 dB and 15.5 dB, respectively, which makes the SKY65364-11 ideal for medium power microwave links such as 900 MHz Industrial, Scientific, and Medical (ISM) band applications. The module also has a shut-down 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-Mounted Technology (SMT) package, which allows for a highly manufacturable low-cost solution. The device package and pinout for the 28-pin MCM are shown in Figure 1. A block diagram of the SKY65364-11 is shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.

A Single-Pole Triple-Throw (SP3T) switch selects between the receive, transmit, and transmit bypass paths. The module has a shut-down mode to minimize power consumption. Three digital input pins (EN, TR, and BYP) are used to select between transmit, transmit bypass, receive, receive bypass, or shutdown mode. Transmit Path The transmit path contains a Power Amplifier (PA) optimized for saturated performance. The PA output is internally matched for optimum output power and efficiency into a 50 Ω load impedance. The PA output is passed through an harmonic filter before being fed through the SP3T switch. The PA input provides a good return loss into a 50 Ω source impedance. Transmit output power is controlled by the VPC pin, which is normally set to 2.25 V DC voltage. The nominal DC input impedance into the VPC pin is 50 kΩ. Receive Path The receive path contains an LNA with bypass switch. The LNA impedance matching networks are internal to the module and have been optimized for a low NF while maintaining good return losses into a 50 Ω source and load impedance. The receive arm of the SP3T switch and the LNA input are connected to module pins to allow an external filter to be inserted into the receive path. LNA biasing can be independently lowered with an external bias resistor between the RBIAS pin and ground. Operation Mode Control The five SKY65364-11 operating modes are controlled by the three digital p.
