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 […]
A directional coupler can be used to monitor a signal on a RF path. The through path is bi-directional, but it only couples the RF signal in one direction. The coupled path is also bi-directional. A signal into the coupled port will be injected onto the RF path. Coupler models with high coupling values (i.e. […]
JFW model 75S-400 is a 75Ω solid-state RF switch. It has a 1P8T configuration and is available with F female connectors. It is a self-terminating design so all unused ports will self-terminate at 75 Ohms. The switch requires a +12Vdc supply Voltage. It is TTL controlled via eight parallel TTL control lines. TTL high turns […]
JFW model 57ZTT-2.2G is a coaxial impedance matching transformer. It operates 5-2200MHz. On the 50Ω side it is available with either BNC, N or SMA connectors. On the 75Ω side it is available with BNC, F or N connectors. This matching transformer allows you to connect a 50Ω device to a 75Ω device and have […]
JFW has added several new power divider/combiner models to our website. These 2Way, 4Way and 8Way models cover several common satellite communication bands. All of these models are 50 Ohm reactive design (i.e. Wilkinson design) with SMA female connectors. These models are ideal for fan-in/fan-out signal routing due to their low through path loss and […]
