The Jetfon JTF-24 RF dummy load (50 Ω coaxial termination) with an N Male connector is an essential precision instrument designed for RF test benches, laboratories, and field service work. Operating from DC up to 3 GHz with an impedance tolerance of 50 Ω (±2%), it delivers a pure, non-reactive resistive termination to evaluate transmitters and RF equipment without radiating signals over the air.
Its core function is to absorb RF transmit energy, converting it into heat to eliminate unwanted reflected power back into the output stage. Rated for 2 W continuous RF power dissipation and featuring a low Voltage Standing Wave Ratio (VSWR ≤ 1.2), the JTF-24 protects power amplifier modules against mismatch damage while ensuring repeatable, accurate measurements during transceiver alignment, amplifier testing, and network analysis.
Why Choose the Jetfon JTF-24 Dummy Load?
Unlike standard resistive loads that suffer from reactance and impedance mismatch at higher microwave frequencies, the Jetfon JTF-24 maintains a low VSWR (≤ 1.2) across its entire broadband range up to 3 GHz. Its precision-threaded N-type male connector and low-loss contact surfaces guarantee tight RF shielding and consistent contact repeatability across hundreds of mating cycles.

Frequently Asked Questions
What is the primary purpose of an RF dummy load?
An RF dummy load absorbs transmitted radio frequency energy and dissipates it as heat, preventing signal radiation into the open air while presenting a matched 50-ohm load that shields the transmitter’s final amplifier from high SWR damage.
Can it handle RF signals above 2 W?
No, the continuous power rating is 2 W. Applying higher RF power levels without an external inline attenuator can permanently shift the internal resistance or damage the load.
