　　射频板MYRIAD LMS6002D具有以下优点:

　　The Myriad–RF 1 board is a multi-band, multi-standard RF module, based on the state of the art LMS6002D transceiver IC by Lime Microsystems. It has one RF broadband output, one RF broadband input with digital baseband interface, established via standard connector FX10A-80P. The board also provides the user with pin headers for power supply, reference clock, analog I/Q input/output and SPI interface connections. It contains everything needed for it to be connected to baseband (BB) chipsets, FPGAs or to run in an standalone mode.

　　The Myriad-RF 1 board enables developers implement their products for a wide variety of wireless communication applications quickly and efficiently, given the flexibility of the solution. In addition, the designer can make use of the freely available ready-made board implementation, modify and manufacture to accelerate the development time.

　　Summary

　　Transceiver                             LMS6002D

　　RF Bandwidth (BW)                300 MHz to 3800 MHz

　　Baseband BW                          Programmable (16 selections); 0.75 – 14 MHz, Bypass mode

　　RF Module Control                    Via SPI interface

　　Analog Inputs                          I/Q differential analog input for transmitter

　　Analog Outputs                        I/Q differential analog output from receiver

　　Reference Clock frequency         23 – 41 MHz  

　　Input Voltage                           5 V(recommended)

　　The power pins are described in detailed the Myriad-RF development manual.

　　Output and Input

　　The figure and table below provide key Input/Output configurations, connector assignments and desions. The analog differential IQ interface is available on Myriad-RF board and provided via X3 and X4 connectors. X6 and X7 are the RF connectors for receive input and transmitter output, clearly marked in the picture. The board is tuned to support band 1 (Tx 2140 MHz and Rx 1950 MHz) as well as broadband operation. The front end switches are configurable for selecting Receiver inputs and Transmitter outputs via GPIO’s which in turn can be controlled via the X3 connector.

　　Communication

　　The LMS6002D register are controlled via SPI interface. The SPI interface can be established via digital connector X3 or external connector X9.

　　Configuration

　　The Myriad-RF 1 board is pre-configured to work on UMTS band-1, the most common band used by 3G communications equipment. By connecting the device to a computer it can be configured to run on any mobile frequency band or standard. This can be done by setting up the LMS6002D registers to the required frequency, gain or BB bandwidth setting using an open source graphical user interface (GUI)
