TRS1-23-75+
CASE STYLE: AT577
Pricing: $1.75 (QTY 100)
Product Overview
The TRS1-23-75+ is a balanced-to-unbalanced 75Ω transmission line transformer, 0.2” x 0.2” x 0.2” in size. This rugged, wire welded, rectangular core design is rated for up to 0.5W maximum power, in an aqueous washable case suitable for both RoHS and tin/lead solder systems.
Feature
Very wide bandwidth
Advantages
10-2200 MHz bandwidth covers CATV (forward & return), medical wireless and D2A/A2D, and other communications applications 0.4 dB amplitude and 3° phase unbalance aid rejection of even harmonics (in push-pull amplifiers) and common mode signals (when used as a balun)
Excellent amplitude and phase unbalance
Good return loss
Provides excellent matching for 75Ω circuitry
Low and flat insertion loss
Consistently low signal loss, ±0.2dB across all 50-1000 MHz CATV bands
