Bad output VSWR of a low noise amplifier (LNA) can be an issue when being connected to devices in a RF assembly. The amplifier’s high VSWR creates an impedance mismatch that can lead to excessive ripple in the through loss of the RF assembly. A common solution is to add a fixed attenuator on the […]
JFW has added a new 75 Ohm relay programmable attenuator to the website. The attenuator operates DC-2150MHz with attenuation range 0-63.5dB x 0.5dB steps. It is available with 75 Ohm BNC, F or N female connectors. We offer the attenuator as a stand alone model or as an attenuator assembly with Ethernet control. The attenuator […]
JFW model 50P-2070 SMA is a TTL controlled solid-state programmable attenuator. It has attenuation range 0-63.75dB x 0.25dB steps. It operates 30-3000MHz and is rated for +27dBm. It is available with 50 Ohm SMA female/female or SMA male/female connectors. Documentation: Data Sheet Outline Drawing TTL Control The attenuator has eight individually controlled steps: 0.25dB, 0.5dB, […]
JFW has three new 50 Ohm termination models. All three new models are available with N or SMA connectors (male or female). The termination models are rated for up to 100 Watts average of input power. The terminations have mounting holes on both ends. They are also available with optional brackets that allow the attenuator […]
All three new models are available with N or SMA connectors. The connectors can be configured as male/female or female/female. The attenuator models are uni-directional. Forward power handling of 100 Watts average and reverse power handling of 20 Watts average. The attenuators have mounting holes on both ends. They are also available with optional brackets […]
JFW has added several new transceiver test system models that cover the HF band. These models are configured as full mesh with a step attenuator on each path through the mesh. These models can be used to connect several HF band radios together in a closed environment. This type of testing environment could be used […]
JFW has added a new 5 Watt resistive power divider/combiner models to the website. All of these 50 Ohm power divider models operate DC-6 GHz. They can handle 5 Watts average (with conduction cooling) and 3 Watts average (without conduction cooling). model 50PD-944 SMA | 2-Way, 5 Watt, DC-6 GHz model 50PD-905 SMA | 3-Way, […]
The RF attenuator is a device that will decrease a signal level by a specified decibel (dB) level while maintaining proper impedance matching at the input port and output port. 50 Ohm and 75 Ohm are the two most common impedance types for RF attenuators. BNC, N, SMA and TNC are common types of coaxial […]
JFW has just added five new USB attenuator models to the website. All five models are 4 channel USB attenuators. Each attenuator is individually controlled using our GUI test software. They have a 50 ohm impedance and are available with SMA female connectors. 4 Channel USB Attenuator Models: 50P-2089 SMA (0-95 x 1dB, 200-6000MHz) 50P-2137 […]
JFW has a new 50 Ohm 4 channel USB attenuator to help automate your RF testing. JFW model 50P-2089 SMA operates from 200-6000Mhz with attenuation range 0 to 95dB by 1dB steps. All four attenuators are individually controlled. Test software is provided with the USB attenuator. If you would like to integrate the USB attenuator […]
