Agilent Technologies introduces next-generation FBAR transmit filter for US PCS band mobile phones, data cards
Agilent Technologies today announced a higher-performance film bulk acoustic resonator (FBAR) full-band transmit filter for handsets, data cards and other wireless products operating in the US PCS (personal communications service) frequency band. Compared with full- band surface acoustic wave (SAW) transmit filters offered by competitors, Agilent's FBAR filter provides superior performance in an equivalent or smaller package.
The Agilent ACPF-7003 features higher rejection – 35dB minimum, 45dB typical in the 1930-1990MHz receive band – than Agilent's widely used ACPF-7002 full-band filter. It also offers lower maximum insertion loss over portions of the 1850-1880MHz transmit band and improved input and output match to 50Ω.
In typical CDMA handset architectures, the transmit filter is incorporated between the driver amplifier and the power amplifier to reduce noise in the receive band, thereby enhancing receiver sensitivity. The high rejection capability of Agilent's miniature FBAR transmit filter keeps out unwanted signals, and its low insertion loss increases transmitter efficiency and performance.
