June 2012 Doc ID 023285 Rev 1 1/8 8 DCPL-WB-02D3 Wide-band, dual-path directional coupler with integrated 50 ohm loaded isolated port Datasheet − production data Features ■ 50 Ω nominal input / output impedance ■ Wide operating frequency range: – 2400 MHz-5850 MHz ■ Low insertion loss ■ High ESD ruggedness ■ Lead-free CSP ■ Small footprint: 1670 x 1440 µm ■ Very low profile (< 600 µm after reflow) Benefits ■ High RF performance ■ RF module size reduction Applications Multi-band equipment such as: ■ Power amplifier module ■ Front end module ■ WLAN Figure 1. Pin configuration (bump view) Description The DCPL-WB-02D3 is a wide-band, dual-path directional coupler designed to measure transmission output power in WLAN applications. This dual path CPL has been customized for wide-band operating frequencies (2G/5G WLAN) with low insertion losses in the transmission bandwidth (2400 MHz - 5850 MHz). This device is built with two different RF couplers (one dedicated to LB, the other dedicated to HB) sharing the same coupled ports. Isolated port is loaded with an integrated 50 Ω resistor. The DCPL-WB-02D3 has been designed using STMicroelectronics IPD (integrated passive device) technology on non-conductive glass substrate to optimize RF performance. The device is delivered 100% tested in tape and reel. Flip Chip (7 bumps) LB Path HB Path B1 C2 HB in 1 2 3 B1 A C CPLD 50 Ω LB out GND LB in GND B HB out www.st.com |
