Need a compact Half Height Waveguide Coaxial Adapter for your 0.38-0.5GHz UHF communications or radar system? As Foreign Trade Director at Xi'an Weitian Electronic Technology Co., Ltd., I frequently hear from U.S. engineering teams that standard UHF waveguide components are simply too bulky for modern compact transceiver designs — especially in airborne and vehicular platforms where every cubic inch matters.
Our BJ5 Waveguide to N Type Adapter addresses this directly. The half-height waveguide port has a narrow dimension exactly one-half that of a standard rectangular waveguide, significantly reducing overall volume while maintaining full electrical performance. This 0.38-0.5GHz Waveguide Coaxial Transition delivers VSWR ≤1.2 and insertion loss ≤0.2 dB across the entire UHF band, with an N-type (female) connector that is the industry standard for low-UHF RF systems in the United States.
This End Launch Waveguide Adapter is machined from aluminum with a black anodized finish, offering lightweight construction with corrosion resistance — ideal for field-deployed and mobile applications. We manufacture in-house under an ISO 9001:2015 certified quality management system, and every unit is RF tested before shipment. Custom half-height waveguide dimensions are available on request.
| Parameter | Specification | U.S. Market Localization Note |
|---|---|---|
| Waveguide Standard | BJ5 (Half-Height Rectangular) | Low-UHF band; half-height narrow dimension = 50% of standard rectangular waveguide |
| Frequency Range | 0.38 – 0.5 GHz | Covers UHF communications and radar bands common in U.S. systems |
| VSWR | ≤ 1.2 | Measured across full 0.38-0.5GHz band |
| Insertion Loss | ≤ 0.2 dB | Including connector and transition loss |
| Average Power | ≤ 50 W (CW) | Sufficient for UHF transceiver and test applications |
| Connector Type | N-K (N-type Female) | N-type is the dominant UHF connector standard in U.S. military and commercial RF systems |
| Body Material | Aluminum | Lightweight — preferred for airborne, vehicular, and portable UHF equipment |
| Surface Finish | Black anodized | Corrosion-resistant; matte black reduces visual signature for field use |
| Waveguide Port | Half-height (reduced narrow dimension) | 50% narrower than standard rectangular waveguide; custom sizes available |

| Customization | Half-height waveguide sizes, connector types, finishes | Designed to order based on customer specifications |
| U.S. Market Segment | Buyer Type | Local Pain Point | Our Product Advantage (Quantified) |
|---|---|---|---|
| Defense & Military Communications | UHF radio manufacturers, military transceiver integrators | Standard UHF waveguide adapters are too bulky for manpack and vehicular radios; need low-profile, low-weight solutions | Half-height design reduces waveguide narrow dimension by 50%; aluminum construction minimizes weight; VSWR ≤1.2 ensures efficient power transfer in field radios |
| Radar & Remote Sensing | Weather radar builders, air surveillance radar integrators | UHF radar front-ends require low insertion loss to maximize receiver sensitivity; bulky components complicate antenna feed layouts | IL ≤0.2 dB across 0.38-0.5GHz preserves signal-to-noise ratio; compact half-height profile simplifies feed network routing; pairs with Log Periodic Antenna in UHF direction-finding arrays |
| Broadcast & Telecom Infrastructure | UHF transmitter manufacturers, broadcast equipment integrators | Need reliable, low-loss waveguide-to-coax transitions for high-power UHF transmitters with limited rack space | 50W CW power handling; N-type connector compatible with mainstream U.S. UHF transmitter hardware; black anodized aluminum dissipates heat efficiently |
| Test & Measurement | UHF test equipment builders, university RF labs, calibration houses | Require traceable, consistent performance for UHF band measurements; standard waveguide adapters take up valuable bench space | VSWR ≤1.2 and IL ≤0.2 dB provide stable measurement references; compact size saves bench real estate; works with Waveguide Load for terminal calibration and Standard Gain Horn Antenna for gain transfer measurements |
Q1: What is the difference between a half-height and a standard waveguide-to-coaxial adapter? A: A half-height (or reduced-height) Waveguide Adapter has a waveguide port whose narrow inner dimension is exactly one-half that of a standard rectangular waveguide. This reduces the overall physical volume and weight, making it suitable for space-constrained applications such as airborne, vehicular, and manpack equipment. The electrical performance — including VSWR and insertion loss — is maintained through optimized transition design. We also offer standard-height and Orthogonal Waveguide Coaxial Adapter configurations for applications where full-height waveguide is required.
Q2: What connector types can you supply for this BJ5 half-height waveguide adapter? A: The standard configuration is N-K (N-type female), which is the most common connector for UHF-band systems in the United States. Other connector types can be evaluated on request. All connector options undergo the same in-house RF testing as our standard products.
Q3: Can you customize the half-height waveguide size or finish? A: Yes. Half-height waveguide dimensions can be customized to your specific requirements. We also offer alternative materials and finishes beyond the standard black anodized aluminum. All custom configurations are designed and tested in-house, and datasheets can be provided upon request.
