UMTS Band 25, Band 1/4 Rx Diplexer
The Broadcom ACFM-2021 is a highly miniaturized diplexer device designed to allow a common antenna to be used for simultaneous reception of Band 1 (or Band 4) and Band 25. The device also enables co-banding between UMTS Band 1 and Band 4.
In addition to maintaining high isolation between Band1 or 4 and Band 25 Rx signals, the ACFM-2021 also provides high rejection of nearby RF interferences to minimize intermodulation products.
Low insertion loss in the Rx pass bands maximizes receiver sensitivity. The excellent power handling capability of FBAR bulk-mode resonators supports the high linearity needed for modern mobile devices.
