What are the key features of 73252-0090?
- 2.92 mm (K-connector) interface supports operation up to 40 GHz, enabling millimeter-wave and microwave applications
- 50 Ω characteristic impedance ensures minimal reflections and VSWR in precision RF signal chains
- Snap-coupling mechanism allows fast mating and unmating cycles without threaded hand-tightening for ATE applications
- Female (jack) contact gender mates with standard 2.92 mm plug cables and RF test fixtures
- Compact body measuring 0.223 inch × 0.430 inch suits dense panel-mount and chassis-mount RF routing designs
What is 73252-0090 used for?
The Molex 73252-0090 2.92 mm RF jack is used in high-frequency test and measurement equipment, vector network analyzers, spectrum analyzers, and microwave point-to-point radio modules where signal integrity must be maintained from DC up to 40 GHz. Its snap-coupling design speeds up connect/disconnect cycles in automated test equipment (ATE) systems that require high throughput without mechanical wear from threaded interfaces. It is also deployed in aerospace radar front-ends and 5G millimeter-wave phased array test fixtures that demand low-loss 50 Ω coaxial transitions.

Frequently Asked Questions
Up to what frequency can the Molex 73252-0090 2.92 mm connector reliably operate in a 50 Ω RF system?
The 2.92 mm (K-connector) interface of the Molex 73252-0090 supports operation from DC up to 40 GHz while maintaining a VSWR below 1.35:1 across the full frequency range. This makes it suitable for Ka-band radar, 5G millimeter-wave test systems, and broadband microwave applications where SMA connectors (18 GHz max) are insufficient.
How does the snap-coupling mechanism of the 73252-0090 compare to threaded K-connectors in ATE environments?
The snap coupling of the 73252-0090 allows mating in under 1 second without rotating a threaded hex nut, enabling automated test equipment to achieve cycle rates of more than 500 connections per hour. Threaded 2.92 mm connectors require 3–5 inch-pound torque and 3–5 seconds per mate, significantly slowing high-throughput ATE wafer-probe or module test setups.
For a 5G FR2 (24–40 GHz) phased array test board, how does 73252-0090 compare to 2.4 mm connectors?
The 2.92 mm 73252-0090 is optimized for up to 40 GHz, which covers the full 5G FR2 band (24.25–40 GHz), and is physically smaller than 2.4 mm connectors (which reach 50 GHz). For FR2 testing at up to 40 GHz, the 73252-0090 is lower cost per port than a 2.4 mm solution while providing equivalent insertion loss below 0.5 dB at 40 GHz on a well-matched PCB launch.
What lead time and procurement planning considerations apply to the Molex 73252-0090?
Molex quotes a factory lead time of 14 weeks for the 73252-0090, which is typical for precision 2.92 mm coaxial connectors. Engineers should place blanket purchase orders 3–4 months ahead of NPI builds and verify stock at authorized distributors such as Mouser, Digi-Key, and Arrow to avoid delays on prototype boards where even 10–20 units are needed on short notice.
