Leading low magnetic field MRI, Physicist Dr. Matthew Rosen
of Harvard Medical School briefly
discusses his experience with applying NF's advanced signal-to-noise technology into his work.
Noise figure essential for NMR/MRI
applications
Recovery time is very short
Ideal for signal detection from 100 kHz to 3 MHz
In signal amplification in NMR and MRI, both low noise performance and recovery time specifications
are important.
If a voltage beyond the input range is applied, the amplifier will be temporarily disabled for
protection.
These CMP-series amplifiers achieve superior performance by emphasizing both the noise figure value as well as having a exceptionally short recovery time to return from disabled mode to normal operation.

| Model | Frequency range | Recovery times | Noise figure | Voltage gain (Output load condition: 50Ω) | Available Magnetic Field |
|---|---|---|---|---|---|
| CMP61748 | 10M to 500MHz | 3µs | 1.5 dB @300MHz | 40dB or 34dB | 1.0 T/1.5 T/3.0 T/7.0 T |
| CMP61748-2 | 1M to 250MHz | 5µs | 1.0 dB @200MHz | 40dB | 0.5 T/1.0 T/1.5 T/3.0 T |
| CMP61665-1 * | 20kHz to 10MHz | 50µs | - | 40dB | Up to 0.2 T |
| CMP61665-2 * | 100k to 50MHz | 10µs | 0.7 dB @50MHz | 40dB | 0.5 T/1.0 T |
* Effortless mounting due to the multi-channel design and ultra-compact size. (External dimensions: 40x50x12mm)
A coupling board that simultaneously delivers power to eight units and a dedicated low-noise DC power supply ( + 15 V, 1.2 A ) are also available as options.
Overall size reduced by 55% compared to the SA-230F5
