BT4025 Features & Benefits

Overview

BT4025 is a bias tee (also called a bias T) 3-port device with N Type and BNC jacks that are ideal for or injecting DC current into RF transmission lines. Covering all applications within the 10-3500 MHz and 3500-4000 MHz ranges, this Bias T can pass up to 1.5 Amps of DC current with excellent electrical performance.

Electrical

The heart of the unit is a precision designed and etched microstrip circuit on a low-loss, high-frequency, dielectric substrate. Electrical performance is highlighted by 0.35 dB max insertion loss, 40 dB min RF-DC isolation, and 1.20:1 max VSWR. Narrow band RF performance over your frequency range may be even better. 100W max RF input power, 100V max DC voltage, and 1.5 Amp max DC current ensures optimal performance for all of your DC-injection requirements.

Mechanical

The BT4025's T-Style housing allows convenient coaxial cable access to all connector ports. Mechanical features include precision CNC, brass, 50 ohm Type N female coaxial connectors with tri allow plating to ensure tarnish resistance and low PIM operation. Connector pins are gold plated phospher bronze for reliability and low contact resistance.Virgin electrical grade PTFE support insulators captivate the contact pins enabling trouble free coaxial connector mating. Long term operation and superior shielding is assured by the rugged CNC machined aluminum housing with clear chemical film finish. Secure mounting is provided by two 0.125" dia (3.18 mm) through holes. RoHS construction includes no-lead solder and a finish free of hexavalent chromium.

Physical

Housing dimensions are 1.98" wide by 1.98" deep by 0.88" high (50.3 x 50.3 x 22.2 mm). The N Type female (jack) connectors extend 0.65" (16.3 mm) from the housing. Operating temperature range is from -65°C to +85°C. Weight is 160 grams. See N Type and BNC Bias T outline drawing for more information.

Applications

The BT4025 Type N female (jack) and BNC, 1.5 Amp, high isolation Bias Tee is ideal for a wide range of wireless radio frequency microwave applications where you must remotely insert DC current into an RF/microwave transmission line, often to power a low noise amplifier or active antenna.
