1 / 14 page WS7808QD Will Semiconductor Ltd. 1 Oct. 2017_V1.0 WS7808QD 0.1GHz – 3GHz DP8T Diversity Receive Antenna Switch Descriptions The WS7808QD is a dual single-pole, four-throw (2xSP4T) with Mobile Industry Processor Interface (MIPI) controlled antenna switch designed specifically for receive diversity in carrier aggregation applications. The device is optimized for broadband performance. Using advanced switching technologies, the WS7808QD maintains low insertion loss and high isolation for all switching paths. The high linearity performance and low insertion loss achieved by the WS7808QD makes it an ideal choice for carrier aggregation applications in both main and diversity antenna switching. The switch also exhibits excellent second/third order intermodulation distortion (IMD2/IMD3) performance. Switching is controlled by an integrated MIPI decoder. The two switches can be configured independently. There are separate registers for each SP4T. No external DC blocking capacitors are required on the RF paths if no DC voltage is applied to those paths. The WS7808QD is manufactured in a compact, 2.0 x 2.4 x 0.55 mm, 18-pin surface-mount Quad Flat No-Lead (QFN) package. Features Working frequency up to 3 GHz Single, positive DC power supply (2.4 to 3.1 V) Integrated programmable MIPI interface using separate registers for ANT_A and ANT_B bands Dual antenna ports can be connected externally to a diplexer Small QFN (18-pin, 2.0 x 2.4 x 0.55 mm) package Applications Cell phones Tablets Other RF front-end modules http//:www.sh-willsemi.com QFN2.0x2.4-18L(Bottom view) 1 2 3 4 14 13 12 11 10 9 8 5 6 7 VDD RFA1 RFA3 NC VIO SDATA SCLK RFA2 RFA4 NC ANT_B 15 16 17 18 ANT_A RFB1 RFB2 RFB3 RFB4 NC NC Pin configuration (Top view) C* C = Device code * = Month code(A~Z) Marking (Top view) Order information Device Package Shipping WS7808QD-18/TR QFN 2.0x2.4-18Q 3000/Reel &Tape |
