Ultra Wideband NCR2-Series RF Transformer 50 3W Up to 18 GHz The Big Deal Microwave Frequency Balun Ultra-Wideband Frequency Coverage, Generic photo used for illustration purposes only from 3.5 up to 18 GHz CASE STYLE: NF1846-1 Miniature Size LTCC Package Product Overview The Mini-Circuits NCR2 family of ultra-wideband balun transformers covers a frequency range spanning 3.5 to 18 GHz with an impedance ratio of 1:2. They are commonly used for unbalanced to balanced applications. LTCC construction provides exceptional reliability, thermal stability, and a high degree of repeatability. A small footprint (0.08 x 0.10) offers flexibility of integration with RF integrated circuits. Key Features Feature Advantages The NCR2 family of LTCC baluns covers many popular microwave frequency bands Ultra-wide bandwidth and is ideal for applications such as satellite communications, point to point radio, and electronic surveillance. Low Temperature Ceramic Co-fired construction offers a high degree of repeatability, LTCC construction temperature stability, and high power handling capabilities. Miniature footprint, The miniature footprint of these LTCC baluns makes them easy to integrate with RF inte- 0.079x0.098x0.035 grated circuits. Notes A.
