The RMS-11 is a low distortion, wide dynamic range, single-chip mixer suitable for RF-IF down conversion in HF and VHF receivers, second mixer in DMR base stations, DC-base band conversion, quadrature modulation And demodulation as well as Doppler detection.
The RMS-11 provides a +24 dBm third-order intercept point for -10 dBm LO power consumption without the need for a high-power LO driver and without the corresponding shielding and isolation issues, resulting in improved performance over passive mixers System performance, reduce system cost.
The mixer is designed for single-supply operation, RF, IF and LO ports with DC isolation capacitors, easy to use. RF and LO inputs operate up to 1900MHz. The IF output is a single-ended voltage output. With 250 MHz output bandwidth. A single resistor connected between pins OUT and FB is used to set the gain.
The amplifier has low DC offset characteristics, which can be used for DC - base band frequency conversion and quadrature amplitude demodulation and other DC-coupled applications.
The mixer's output amplifier and the best source impedance, the mixer SSB noise figure at 70 MHz 10.3 dB. Unlike passive mixers, the RMS-11 does not have insertion loss, eliminates the need for an external duplexer, and requires no passive termination.
