説明
PRODUCT OVERVIEW
The KJ-05-BK-01-Au is a 50 Ω 2.92mm (K Band) jack receptacle specified from DC to 40 GHz. It provides a straight coaxial interface for a PCB RF connection, combining a threaded mating port with the surface-mount configuration identified in the engineering drawing.
The 1/4-36 UNS-2A external thread supports screw-on mating engagement. A 6.00 mm square body and 12.50 mm overall length define the space required around the connector. Four body posts and a central PCB contact provide the mechanical and signal interface shown in the recommended board layout.
The assembly uses a gold-finished brass body, a gold-finished beryllium copper (BeCu) contact and a PEEK insulator. Its 1.61 g weight and specified -65 °C to +165 °C temperature range support component selection for compact microwave modules and board-level RF test hardware.
For implementation, review the connector geometry together with the PCB stack-up, transmission-line transition and assembly process. The reference PCB pattern may require adaptation to the board design; the complete mounted RF path should be verified over the intended operating band.
Features
- DC to 40 GHz frequency coverage: a 50 Ω connector option for broadband RF and microwave board interfaces.
- Threaded coupling: a 1/4-36 UNS-2A external thread provides screw-on mating engagement.
- Compact board footprint: the 6.00 mm square body helps plan connector placement in dense RF layouts.
- Straight PCB configuration: the mating axis and central PCB contact follow a straight path; four body posts locate the receptacle at the board.
- Gold-finished metal components: the body is brass and the contact is BeCu, with gold finish specified for both parts.
- PEEK insulation: the drawing identifies the insulator material and a -65 °C to +165 °C assembly temperature rating.
- Documented integration geometry: the drawing includes connector dimensions and a reference PCB pattern for layout review.

Applications
Potential uses for this PCB receptacle include the following RF development and equipment interfaces. Selection depends on the required frequency band, mating arrangement and completed board performance.
- Microwave test and measurement: board-level RF ports for connecting a device under test to external test hardware.
- Laboratory evaluation fixtures: prototype and characterization boards that require a threaded 2.92mm (K Band) interface.
- SATCOM RF module development: candidate PCB interfaces for microwave signal paths within the specified operating range.
- Compact high-frequency PCB modules: board-to-coaxial transitions where a straight receptacle and small body suit the mechanical layout.
Validate the connector-to-board transition, assembly process and system requirements for the intended application.
