Description
The SKY77491-15B is a transmit and receive Front End Module (FEM) designed in a low profile (1.2 mm), compact form factor for quad-band cellular handsets comprising GSM850/900, DCS1800, and PCS1900 operation. It provides a complete transmit VCO-to-Antenna and Antenna-to-receive SAW filter solution. The FEM also supports Class 12 General Packet Radio Service (GPRS) multi-slot operation.
Specifications and features
• High efficiency:
- GSM850: 43%

- DCS: 40%
- PCS: 40%
• Internal ICC sense-resistor for iPAC
• Closed loop iPAC or open loop operation with external PAC circuit
• Input/Output matching 50 ohms internal (with DC blocking)
• TX-VCO-to-antenna and antenna-to-RX-SAW filter RF interface
• TX harmonics below -33 dBm·
• PHEMT RF switches afford high linearity, low insertion loss, and less than 20 µA supply current in receive modes
• Small outline: 8 mm x 10 mm
• Low profile: 1.2 mm maximum
• Low APC current: 20 µA
• Gold plated, lead-free contacts
• High impedance control inputs: 15 µA, typicalApplication Scenarios
