The Bird 8135 Termaline Coaxial Load Resistor 4000 MHz, 150 Watts is a portable, general purpose 50 ohm coaxial transmission line termination. It is a self-contained unit requiring no outside power source or additional equipment. This coaxial load resistor provides an accurate, dependable, and practically non-reflective termination for adjustment, standby, and testing of transmitters under nonradiating conditions. The Model 8135 can absorb up to 150 watts continuously and dissipate it harmlessly as heat over a frequency range of dc to 4000 MHz. It is designed to show low reflectivity throughout this range. The VSWR will be 1.1 to 1.0 maximum from dc to 1000 MHz, 1.2 to 1.0 maximum from 1000 to 2500 MHz and 1.3 to 1.0 maximum from 2000 to 4000 MHz.
Industry standard portable Bench load for general purpose mobile and base station RF testing up to 4 GHz
Oil-assisted convection cooling for safe, continuous operation up to 150W full rated power
Quick Change (QC) connectors to minimize the need for adaptors when making critical measurements
Rugged housing with handle and rubber feet for trouble-free operation in the most demanding environments
