Applications & Customer Value
Automotive RF Module Development
Engineers can access individual coaxial paths during prototype evaluation. The dual SMA ends connect to separate measurement ports while the device retains its original HFM interface.
Vector Network Analyzer Testing
Each SMA branch can connect to a compatible VNA port for channel measurements such as insertion loss and return loss, subject to the test setup and specified operating range.
Automotive RF Test Fixture Integration
SMA based measurement fixtures can be connected to HFM equipped devices without replacing the connector on the automotive module.
Dual Channel RF Signal Verification
Separate SMA terminations allow channel by channel checks and comparison of measurement results during RF troubleshooting and development.
Product Features
Dual Cavity HFM Interface
One compact HFM housing contains two coaxial connections, keeping both RF paths together at the equipment interface.
Independent SMA Channel Terminations
Two SMA connectors provide separate RF channel access, with male and female termination options available.
Rosenberger Z Code Connector Options
AMS11B-1M4Z5-Z and AMK16B-1M4Z5-Z provide distinct male and female mating configurations with Z Code keying.
Dacar302-4 Coaxial Construction
Two Dacar302-4 coaxial cable branches can be routed to separate instrument ports and terminated independently.

Product FAQ
Q1: What is a dual cavity HFM to SMA cable?
It connects two coaxial channels in one HFM connector to two individual SMA connectors, allowing independent RF signal access.
Q2: How do AMS11B-1M4Z5-Z and AMK16B-1M4Z5-Z differ?
AMS11B-1M4Z5-Z is the HFM dual cavity male connector; AMK16B-1M4Z5-Z is the female version. Their mating structures differ.
Q3: Can this cable connect to any SMA test instrument?
The SMA gender must match the instrument port. Confirm mechanical mating and RF specifications before use.
Q4: What frequency range and impedance does this assembly support?
The supplied product information does not confirm an assembly frequency range or impedance. Verify these parameters from the cable and connector specifications and relevant tests.
Q5: Can Premier Cable manufacture custom HFM to SMA assemblies?
Yes. Premier Cable supports OEM lengths, connector combinations, channel labeling, drawing review, prototypes and volume manufacturing.
