Item Type: RF Mixer Board_x000D_Material: PCB_x000D_RF Input: 1.5-4.5GHz_x000D_IF Output: DC-1.5GHz_x000D_Conversion Loss: 8.5dB_x000D_Noise Figure: 8.5dB (SSB)_x000D_Local Oscillator Input: 13dBm_x000D_Port Isolation: _x000D_LO to RF: 40dB (typical)_x000D_LO to IF: 35dB (typical)_x000D_High Input 1P3: 18dBm_x000D_High Input P1dB: 8dBm 1DIFFERENTIAL CIRCUIT: Both frequency inputs are applied to the differential circuit, so neither the input signal nor the product signal appear at the output. 2DOUBLE BALANCED: This mixer module is more complex than unbalanced and single balanced mixer, with good stability, requiring higher drive levels. 3GOOD ISOLATION: The mixer module has good isolation at the RF and IF ends relative to the LO end, so the requirements for the IF filter are not high. 4HIGH PERFORMANCE: The RF input is 1.5?4.5GHz, IF output is DC?1.5GHz, and the frequency conversion loss is small, with low noise and less interference. 5EASY TO INSTALL: The double balanced mixer module has compact size with standard mounting holes for easy installation and does not take up space.1 x RF Mixer Board
