LMX2594 Module Frequency Synthesizer Development Board w/ Case PLL 10M-15GHz Microwave Signal Source

Description:

-LMX2594 is a high-performance broadband synthesizer that can generate any frequency in the range of 10MHz to 15GHz without using an internal doubler, so there is no need to use sub-harmonic filters. The high-performance PLL with a quality factor of -236dBc/Hz and a high phase detector frequency can achieve very low in-band noise and integrated jitter. The high-speed N divider has no prescaler, which significantly reduces the amplitude and number of spurs. There is also a programmable input multiplier that reduces spurs on integer boundaries.
-LMX2594 allows users to synchronize the output of multiple devices, and can be used in situations where a delay is required between input and output. The frequency ramp generator can synthesize up to 2 ramps in the automatic ramp generation option or the manual option to achieve maximum flexibility. The frequency can be accelerated to more than 20μs through the fast calibration algorithm.
-LMX2594 adds support for generating or repeating SYSREF (compliant with JESD204B standard), making it an ideal low-noise clock source for high-speed data converters. In this configuration, a fine delay adjustment (9ps resolution) is provided to solve the delay difference of the board trace.
-The output driver in LMX2594 provides up to 7dBm output power when the carrier frequency is 15GHz. The device uses a single 3.3V power supply and has an integrated LDO, eliminating the need for an on-board low-noise LDO.

Details:
1. The LMX2594 frequency synthesizer development board is built by senior engineers with full reference to the design of the official version; the PCB has a beautiful appearance, reasonable layout and design, and exquisite materials.
2. Module external control IO is basically external, and is basically compatible with the interface of the official evaluation board.
3. The external signal terminals of the module are:
Output signal: RFA's A&B, RFB's A&B
Input signal: SysRefReq, SYNC, clock input A&B (external clock needs to adjust some components of the PCB board)
4. The module also has a matching aluminum alloy case, which can play an effective shielding effect.
5. Power supply mode: 3.3V (no regulator IC inside the module)

Applications:
-5G and millimeter wave wireless infrastructure
-Test and measurement equipment
-Radar
-MIMO
-Phased array antenna and beamforming
-High-speed data converter clock (support JESD204B)
