Dolph Microwave
High-Power Waveguide to Coaxial Adapters
Choose a right-angle or end-launch adapter, then check the frequency band, coaxial connector and power rating in the same model row. The range covers WR2300 through WR10.
- Combined model coverage
- 0.32–112 GHz
- Connection layouts
- Right angle / end launch
- Listed materials
- Al / Cu
Before you order
Three choices decide the adapter
Where the cable exits
WHPCA identifies a right-angle adapter. WHPECA identifies an end-launch adapter. Check cable clearance and the direction of the waveguide run.
Connector type and gender
The part-number guide includes N, TNC, SMA and 2.92 mm codes, with K for female and J for male. The connector available depends on the selected model.
Power at the operating band
Lower-band rows list up to 1,500 W average power. The WR10 rows list 50 W, 1.4:1 VSWR and 1 dB insertion loss. Do not use one family-wide rating for every adapter.
For bench measurements, compare the waveguide calibration kits. Check the flange size and gasket-fit guide if the mating flange code is uncertain.
For the rest of your setup
Check the cable end at the same time
An adapter order needs both the waveguide flange and the mating coaxial interface. Include the cable connector type and gender so the two sides can be checked together.

Questions before ordering
Does every model handle 1,500 W?
No. Average power is listed by model and frequency band. Use the selected row and include peak power or pulse conditions in the enquiry.
How do I specify male or female?
The original part-number guide uses K for female and J for male. Include the full connector name as well as the code to avoid ambiguity.
