JFW model 75PA-131 F is a 75 Ohm attenuator assembly that can be used to test CATV devices. The attenuator assembly operates DC-1218MHz and contains 32 individually controlled step attenuators with attenuation range 0-95.5dB x 0.5dB steps. Each attenuator has two ports that are both cabled to the rear panel with F female connectors. The […]
JFW model 50T-706 is a 50 Ohm termination that operates DC-18GHz. It is available with TNC male or TNC female. It is rated for 2 Watts average input power. Schematically this part is a 50 Ohm resistor to ground. Connecting this part to an open 50 Ohm port will properly terminate the port with 50 […]
JFW model 50MS-471 is a 6X6 blocking matrix switch that operates 400-7125 MHz. All unused ports are absorptive (i.e. self-terminating into 50 Ohm). It is available with N or SMA connectors. The matrix is constructed using switches on both halves of the matrix. A 6X6 blocking matrix can only have a maximum of 6 active […]
JFW model 50MS-470 is an 4X4 blocking matrix switch that operates 400-7125 MHz. All unused ports are absorptive (i.e. self-terminating into 50 Ohm). It is available with N or SMA connectors. The matrix is constructed using switches on both halves of the matrix. A 4X4 blocking matrix can only have a maximum of 4 active […]
Using a fixed attenuator that matches your bandwidth will reduce you costs. Do not pay for an 18GHz attenuator when a 6GHz attenuator will meet your bandwidth and cost less. 2 Watt fixed attenuators: model 50HFFA-xxx-2/6SMA (DC-6 GHz, SMA) model 50HFFA-xxx-2/8SMA (DC-8.4 GHz, SMA) model 50HFFA-xxx-2/18SMA (DC-18 GHz, SMA) model 50HFFA-xxx-2/26SMA (DC-26.5 GHz, SMA) model […]
JFW has added four new 18GHz DC block models. All four models are inner only type DC blocks with 50 Ohm impedance. They are available with SMA or N type connectors. Model 50DB-081 SMA 10MHz to 18GHz 200Vdc Documentation Model 50DB-083 N 10MHz to 18GHz 200Vdc Documentation Model 50DB-085 SMA 9kHz to 18GHz 50Vdc Documentation […]
JFW model 50P-2101 SMA is a 50 Ohm programmable attenuator with simple to use TTL control. It operates 100MHz to 18GHz and is controlled via parallel TTL lines. Each control line controls 1 of the 7 attenuation sections (i.e. 0.5, 1, 2, 4, 8, 16, and 31.5dB). Activate multiple sections to achieve combinational dB values. […]
JFW has added model 50BR-167 to the website. It is a 50 Ohm manual attenuator in a benchtop enclosure. It operates DC-3.6GHz and has attenuation range 0-110dB x 1dB steps. The unit has three knobs on the front panel. The knobs control three attenuators that are connected in series with each other. The attenuation setting […]
JFW model 50PA-1253 is a 4X8 handover test system that can be used for signal fade testing between wireless devices and network access points. It operates 500-6000MHz with 0-63.5dB x 0.5dB step programmable attenuators. It is a full fan-out configuration (32 total paths) with a programmable attenuator on every path (32 total attenuators). This unit […]
JFW has recently added two new models. They are conduction cooled (aka bolt down) type 50 Ohm fixed attenuators. The enclosure has through-holes for mounting so it can be bolted down to a cooling plate or heatsink. The fixed attenuators are available with BNC, N, SMA or TNC type connectors. Model 50FHSR-XXX-100: 100 Watts average | […]
