Broadband LNAs for Millimeter-Wave Applications in E- and W-Band with High Gain and Low Noise Figure
The waveguide low noise amplifiers of WLNA-XX series comprises waveguide low noise amplifiers designed for full-band amplification of high-frequency RF signals with minimal added noise. These amplifiers offer a low noise figure and high gain across the entire operating band, making them suitable for demanding millimeter-wave applications.
Devices are available for the following frequency bands:
-
60–90 GHz (E-band)
-
75–110 GHz (W-band)
Each unit is supplied with standard waveguide flanges — WR-12 for E-band and WR-10 for W-band — ensuring seamless integration into microwave systems.
Key Features
-
Low noise figure: 3.6 dB
-
High gain: 38 dB (typical)
-
Flat gain across the passband: ±4.5 dB variation
Typical Applications
-
Microwave test and measurement equipment
-
Telecom base stations
-
Full-band radar receiver front ends
Abbreviation code legend (How to order)
When placing an order, please specify the required frequency range and nominal gain value using the following model designation:
WLNA-10-XX — for W-band (WR-10, 75–110 GHz)
WLNA-12-XX — for E-band (WR-12, 60–90 GHz)
Where XX denotes the target average gain in decibels:
“20”, “30”, or “40” dB
Example:
WLNA-10-30 – amplifier for W-band with 30 dB nominal gain
Options with lower gain values are available upon request.
Please contact us for custom configurations tailored to your application.
