50Ω 240 to 770 MHz 1:2 Ratio
The Big Deal
• Tiny size, 0805
• Low insertion loss, 0.2 dB
• Very good amplitude unbalance, 0.5 dB
• Low cost
CASE STYLE: GE0805C-9
Product Overview
Mini-Circuits NCS2-771+ is a miniature ceramic RF balun transformer with an impedance ratio of 2:1,
covering a variety of 50Ω applications from 240 to 770 MHz. This model provides low insertion loss, low
amplitude unbalance, and RF input power handling up to 2W. Fabricated using LTCC technology, it comes
housed in a tiny package (0.08 x 0.05 x 0.04”) and is suitable for high-volume production.
Key Features
Feature
Advantages
Low insertion loss, 0.8 dB
Enables excellent signal power transmission from input to output.
Low unbalance can improve a system’s electromagnetic compatibility by rejecting un-
wanted common-mode noise.
Low amplitude unbalance, 0.8 dB
2W power handling
DC Isolation
Supports a wide range of power requirements
Provides DC isolation between circuits and efficient AC transmission, eliminating the
need for external DC biasing components.
Tiny size, 0805
Accommodates tight space requirements for dense PCB layouts.
