There is a WB-SG-OPT15G available now, see https://www.aliexpress.com/item/4000724122338.html. No modulation feature though. I guess it's based on LMX2594. I wonder if there will be a LMX2595 version later?
Seen a device on eBay already (its not a BG7TBL design) ...
https://www.ebay.com/itm/LMX2595-10MHz-19GHz-RF-Signal-Generator-Frequency-Source-Sweep-OLED-Software-/183730920473- with these specifications
1, LMX2595 chip features
• 10MHz to 19GHz output frequency
• With 100KHz offset and 15GHz carrier
-110dBc/Hz phase noise
• 45fs RMS jitter at 7.5GHz (100Hz to
100MHz)
• Programmable output power
• PLL main specifications
– Quality factor: –236dBc/Hz
– Nominal 1/f noise: –129dBc/Hz
– highest phase detector frequency
– 400MHz integer mode
– 300MHz fractional mode
– 32-bit score N divider
• Eliminate integer boundary spurs with programmable input multipliers
• Output phase synchronization across multiple devices
• Support for SYSREF with programmable resolution of 9ps resolution
• FMCW's frequency ramp and chirp capability
• Less than 20μs VCO calibration speed
• 3.3V single supply operation
2, LMX2595 chip application
• 5G and millimeter wave wireless infrastructure
• Test and measurement equipment
• Radar
• MIMO
• Phased array antenna and beamforming
• High speed data converter clock (supports JESD204B)
Looks like from their SA plot @19GHz - the output level is -26dBm and there seem to be 'lots' of harmonics in the 'same' region
Can you really have a reliable 19GHz source without special design considerations and PCB / microstrip factors implemented for a $385 price tag?
Does anyone have this device or made any tests with a LMX2995 design?
Any feedback much appreciated
