LMX2594 Frequency Synthesizer 10M-15GHz HF Microwave Signal Generator + USB Official Control Board

Product 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. With a high-performance PLL with a quality factor of -236dBc/Hz and high phase detector frequency, it 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 applied when a delay is determined 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 output power up to 7dBm 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.

Module Features:
1. LMX2594 frequency synthesizer development board is built by senior engineers with full reference to the design of the official version; PCB has a beautiful appearance, reasonable layout and design, and made from exquisite materials;
2. Module external control IO is basically external, and is basically compatible with the interface of the official evaluation board;
3. 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 (some components of the PCB board need to be adjusted for external clock);
4. Optional USB official control board. You can use the official control software to control the LMX2594 module through USB, which can realize point frequency and sweep frequency functions;
5. The module also has an aluminum alloy shell, which has an effective shielding effect;
6. Power supply mode: 3.3V (no regulator IC inside the module).
