Description RMS-11 is a low-distortion, wide dynamic range, single-chip mixer suitable for RF-IF downconversion in HF and VHF receivers, other mixers in DMR base stations, DC-baseband conversion, quadrature modulation and demodulation, and 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 problems, resulting in improved performance compared to passive mixers System performance, reduce system cost. The mixer is designed for a single-supply operation, RF, IF, and LO ports with DC isolation capacitors, easy to use. RF and LO inputs operate up to 1900 MHz. 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 - baseband frequency conversion and quadrature
