Introduction
The MAX2116 P1db data is measured at specific combinations of RF and baseband gain over the adjustable range of these two gains. These data can be used to select gain control se...[Details]
In the process of RF transceiver application, adjusting the processing gain (PG) of the direct sequence spread spectrum communication system (DSSS) can obtain excellent anti-noise performance, whic...[Details]
Portable products are generally powered by batteries. Due to cost and size considerations, there is a trend to reduce the number and size of batteries used in design. If the number of batteries is ...[Details]
Abstract:
The signal flow of the external transceiver in the WCDMA/TD-SCDMA protocol is analyzed. The analysis results show that most of the functional modules in the WCDMA/TD-SCDMA external tr...[Details]
1 Introduction
In many communication systems, the base station usually sends a training sequence for the terminal to synchronize with the system. The synchronization here includes time syn...[Details]
