Aerospace Grade Waveguide to 2.92 Type Direct Feed Coaxial Adapter
BJ260
Our company manufactures two types of coaxial waveguide converters
for spacecraft: direct-fed and side-fed.
These converters operate within a broad frequency range from 5.3GHz
to 110GHz. The waveguide end features various rectangular waveguide
ports, including BJ70, BJ84, BJ100, BJ120, BJ140, BJ180, BJ220,
BJ260, BJ320, BJ400, BJ500, BJ620, BJ740, and BJ900. On the coaxial
end, they are compatible with interfaces such as SMA series, 2.92mm
series, 2.4mm series, 1.85mm series, among others. Each model is
designed to support the full bandwidth of its respective waveguide
type.
Key features of these converters include robust construction,
compact size, exceptional electrical performance and consistency,
and lightweight design (≤20 grams). They have been widely adopted
in various spacecraft applications.

Features:
1. Thermal design and micro-discharge suppression: In order to cope
with the heat that may be generated inside the spacecraft and
prevent micro-discharge phenomena, these converters will also be
optimized in terms of thermal design and micro-discharge
suppression.
2. Lightweight design: In order to meet the stringent weight
requirements of spacecraft, space-grade waveguide coaxial adapters
are usually designed to be lightweight and keep the weight at a low
level (e.g., ≤20 grams).
3. Multiple Interface Compatibility: These converters offer
multiple waveguide and coaxial interfaces for compatibility with
different system requirements. For example, the waveguide side may
cover a wide range of models such as BJ70, BJ84, BJ100, etc., while
the coaxial side may be compatible with a wide range of interfaces
such as SMA series, 2.92mm series, and others.
Application:
1. Data transmission: Aerospace-grade waveguide coaxial adapters
are also used in data transmission systems within spacecraft to
ensure fast and accurate data transfer between different
components.
2. Scientific research: In space science experiments, these
converters are used to connect various scientific instruments and
sensors to support observation and research of the cosmic
environment.
