Module combines five individual FBAR filters to produce a totally passive solution for dual-band cellular communications with GPS.

Avago Technologies has developed the first module to combine five individual FBAR (film bulk acoustic resonator) filters to produce a totally passive solution for dual-band cellular communications with GPS. The ACFM-7101 quintplexer module directs PCS and cellular signals from the same antenna without the use of switches and control logic, eliminating the cost and electrical loss of the switch, as well as routing and matching losses, and the space required for this functionality. The result is that GPS-equipped dual-band handsets can be made thinner, the radio-frequency electronics smaller, and at a lower cost to manufacture, with longer overall battery life and improved performance.

The quintplexer module is the latest in a series of technological breakthroughs in FBAR duplexers, enabling Avago Technologies to garner more than 75% of the bulk acoustic wave market according to Strategy Analytics.

The ACFM-7101 uses Avago’s FBAR filter process and innovative microcap bonded-wafer chip scale packaging technology to achieve a small 5 x 8 x 1.3mm module.

This small module size, along with the saving of additional board space for components, routing, and antenna, gives handset designers flexibility in design.

Avago’s quintplexer module is compatible with both the conventional CDMA technology and the WCDMA third generation technology that supports voice, data, images, and video communications at speeds up to 2Mbit/s.

The ACFM-7101 is also an excellent choice for small PC cards, PDAs and other dual-band wireless devices.

‘One of the most exciting aspects of Avago’s new quintplexer module is that in addition to the obvious size advantages of integrating the filters, it optimises the interface between the filters, reducing design complexity and space’, said Bryan Ingram, Vice President and General Manager of Avago Technologies’ wireless semiconductor Division.

‘The industry relies on innovations from companies like Avago to give consumers the phones they want’.

Performance of the ACFM-7101 is specified from antenna port through to the receive port and from the antenna through to the transmit port.

This eliminates customer routing, matching, and switching losses associated with a discrete solution.

Cell duplexer transmit path loss from transmitter input port to antenna output port is a low 2.0dB.

PCS duplexer transmit path loss from transmitter input port to antenna output port is a low 3.0dB.

Avago is currently shipping the ACFM-7101 FBAR quintplexer module to two of the top three CDMA handset manufacturers in production quantities.
