Dual Coupler Fits Tiny Surface-Mount Pack

Even though it is rated for power levels to 150 W, model IPP-8051 is a dual directional coupler from Innovative Power Products that fits into a tiny surface-mount package measuring just 1.50 x 1.00 in. The dual directional coupler features 20-dB coupling factor with coupling flatness of better than ±0.85 dB from 800 to 2500 MHz. The unique design has separate coupled ports for forward and reflected signals and includes internal terminations. It exhibits less than 0.40 dB insertion loss with mainline VSWR of less than 1.25:1 and better than 20-dB directivity across the full frequency range.
