Narrowband Millimeter-Wave Power Amplifiers up to 100 GHz with Flat Output and High Efficiency
The PA-XX series comprises waveguide power amplifiers specifically designed for the narrowband amplification of high-frequency RF signals. These amplifiers deliver consistently high output power across their operating bands, making them ideal for high-performance millimeter-wave applications.
To maximize amplification efficiency, internal 50 Ω matching networks are not used — frequency tuning is carried out during manufacturing. This design approach ensures optimal performance with minimal signal losses. Amplifiers are available for the following frequency bands:
-
35–40 GHz (WR-22)
-
68–77 GHz (WR-12)
-
80–100 GHz (WR-10)
Key Features
-
High output power:
+28 dBm (PA-22-39)
+26 dBm (PA-12-70)
+20 dBm (PA-10-94) -
Flat output across the operating band:
≤ 3 dB power variation
Typical Applications
-
Narrowband radar systems
-
Point-to-point microwave links
-
Test and measurement equipment
-
Scientific and industrial systems
Abbreviation code legend (How to order)
Model numbers follow the format PA-XX-YY, where:
-
XX — waveguide flange type (e.g., 22 for WR-22, 12 for WR-12, 10 for WR-10)
-
YY — central frequency of the amplifier in GHz
Example:
PA-12-70 — amplifier with WR-12 flange, centered at 70 GHz
Custom center frequencies and output power levels can be provided on request.
