| DATA SHEET SKY65338-21: 450-470 MHz Transmit/Receive Front-End Module Applications Tetra radio Remote metering GSM WLL transmitters Description Skyworks SKY65338-21 is a high-efficiency Front-End Module (FEM) that incorporates a transmit and receive path, and an antenna transmit/receive (T/R) switch. The transmit path consists of a high efficiency Power Amplifier (PA) followed by an harmonic filter for rejection of harmonic frequencies. The PA is implemented using Skyworks high reliability Heterojunction Bipolar Transistor (HBT) process and is Class AB biased to provide maximum efficiency with a low spurious output. A high linearity and high isolation Single-Pole Double-Throw (SPDT) switch is used at the common antenna interface between the transmit and receive paths. The receive path is a low insertion loss through-path with input and output ports internally matched to 50 . The device is mounted in a 12-pin, 8 x 8 mm Multi-Chip Module (MCM) Surface-Mounted Technology (SMT) package, which allows for a highly manufacturable low-cost solution. A block diagram of the SKY65338-21 is shown in Figure 1. The device package and pinout for the 12-pin MCM are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.

An active bias circuit provides the input and output stages with excellent gain tracking over temperature and voltage variations. The module operates with positive DC voltages, and maintains high efficiency and good linearity. The nominal operating voltage is 3.6 V for maximum power, but the device can be operated at slightly lower voltages for other mobile applications. The SKY65338-21 is internally matched for optimum linearity and efficiency. The input and output stages are independently supplied using the VCC1 and VCC2 supply lines (pins 12 and 10, respectively). The bias reference voltages for stages 1 and 2 are supplied using common lines VREF1 and VREF2 (pins 5 and 6, respectively). The DC control voltage that sets the bias for stages 1 and 2 is supplied by the VC_BIAS signal, pin 4. Operational Modes The module's receive and transmit modes are configured using the V1 and V2 control signals (pins 9 and 8, respectively). The transmit path provides an harmonic filter and high efficiency PA. The receive path provides a low loss <1 dB bypass between the antenna port and the receive port. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY65338-21 are provided in Table 2. The recommended operating conditions are specified in Table 3 and electrical specifications are provided in Table 4. Typical performance characteristics of the SKY65338-21 are illustrated in Figures 3 through 10. The state of the SKY65338-21 is determiend by the logic provided in Table 5.

The Evaluation Board schematic diagram is shown in Figure 11. An assembly drawing for the Evaluation Board is shown in Figure 12 and the layer detail is provided in Figure 13. The layer detail physical characteristics are noted in Figure 14. Table 6 provides the Bill of Materials (BOM) list for Evaluation Board components. Circuit Design Considerations The following design considerations are general in nature and must be followed regadless of final use or configuration: 1. Paths to ground should be made as short as possible. 2. The ground pad of the SKY65338-21 has special electrical and thermal grounding requirements. This pad is the main thermal conduit for heat dissipation. Since the circuit board acts as the heat sink, it must shunt as much heat as possible from the device. Therefore, design the connection to the ground pad to dissipate the maximum wattage produced by the circuit board. Multiple vias to the grounding layer are required. NOTE: A poor connection between the slug and ground increases junction temperature (TJ), which reduces the lifetime of the device.
