TCM9-1+ is an RF transformer module designed by Mini-Circuits

Functions

1. Frequency Range
   Supports a wide frequency range from 2 MHz to 280 MHz , making it suitable for diverse RF signal processing needs across VHF and UHF bands.
2. Impedance Ratio
   Features a 1:9 impedance transformation ratio (secondary to primary), enabling efficient impedance matching between circuits with mismatched impedances (e.g., 50Ω to 450Ω) .
3. Low Insertion Loss
   Exhibits minimal insertion loss (e.g., 0.87 dB typical at 8.8 MHz), ensuring low signal degradation and high transmission efficiency .
4. Balanced-to-Unbalanced Conversion
   Provides balanced (differential) to unbalanced (single-ended) signal conversion, critical for applications requiring symmetry in signal paths.
5. Surface-Mount Design
   Utilizes a compact DB714 surface-mount package (4.06 x 3.81 x 4.06 mm), ideal for space-constrained PCBs .
6. Environmental Compliance
   Compliant with RoHS standards (denoted by the "+" suffix), ensuring eco-friendly manufacturing .
7. High Stability
   Maintains consistent performance across temperature ranges (-55°C to 100°C) and supports DC current up to 30 mA .

Applications

1. RF Circuit Design
   • Impedance Matching: Bridges mismatched impedances in amplifiers, filters, and antenna systems to maximize power transfer .
