The RD2550 reference design is based on the MAX2550 and - Application Notes and Tutorials contains all of the relevant components necessary to design and build a competitive radio solution to support the base-station transceiver (BTS) frequency band: 1920MHz to - EV Kit Software - Technical Support 1980MHz (Rx) and 2110MHz to 2170MHz (Tx). The RD2550 also supports downlink monitoring of surrounding macrocells. This enables the system to select the most suitable operating conditions (power, codes, frequencies, capacity, etc.). General Description The design features the MAX2550 as the main radio frequency (RF) transceiver, along with all components necessary to complete a radio design. These components include the external power amplifiers, duplexers, TCXO, and passive components. Along with the RD2550 reference design, Maxim's complete package includes a performance report to show full compliance to the 3GPP TS25.104 home-area base- Click here for an overview of the wireless components used in a typical radio station standard. In addition to the RD2550, we also have the RD2551, RD2552, transceiver. and RD2553 reference designs, which are based on the MAX2551, MAX2552, and MAX2553 transceivers and cover additional frequency bands and standards. In total, Maxim's highly integrated single-chip femtocell transceiver family covers WCDMA bands 1-6 and 8-10, and cdma2000® band class 0, 1, and 10.
