[AK1222] AK1222 900MHz Low Power Mixer 1. Overview The AK1222 is a low power mixer. RF and LO frequency range coverage from 100 to 900MHz and IF coverage is from 20 to 100MHz. The RF input provides single-ended 50 interface. LO ports are 50 matched and complementary inputs should be decoupled to the ground. IF output ports are differential open drain outputs. The linearity and power consumption performances can optimize with the resistance connected to the BIAS pin. 2.

Application Information •Impedance matching network with LC Figure 22. Impedance matching network with LC Impedance matching network with LC is shown in Figure 22. AK1222 has open drain outputs, so RL1 + RL2 is output load resistance. C11 and L11 compose lowpass filter. C12 and L12 are for highpass filter. C13 is DC blocking capacitor and L13 is RF choke. IFOUTP and IFOUTN pins need power feeding via L11, L12 and L13. The differential voltage from IFOUTP/N can be converted to a single-ended by L11, L12, C11 and C12 properly. The differential impedance (RL1 + RL2) is converted to single-ended output terminating impedance Ro. L11, C11, L12 and C12 are calculated as below. fout is IF output frequency. C11 C12 L11 L12 1 2π * f OUT * RL1 RL2 * RO RL1 RL2 * RO 2π * f OUT For example, in the case of IF Output = 50MHz, Output Load Resistor (Rload) = 2.2k in 50 interface, L11, C11, L12 and C12 are calculated as below. MS1314-E-02 2014/10 - 25 - [AK1222] C11 C12 1 9.6pF 2π * 50 *10^6* 2.2 *10^3* 50 L11 L12 2.2 *10^3* 50 1056nH 2π * 50 *10^6 L13 and C13 should be large enough not to affect the impedance at IF output frequency. In some cases the impedance matching can be optimized by L13 and C13. For example, in the case of IF Output = 50MHz, Output Load Resistor (Rload) = 2.2k in 50 interface, it is recommended to choose 2200nH and 1000pF as L13 and C13. If any correction is needed, it can be adjusted by reducing the value of L13 and C13. These calculated values are approximation. In some cases, some correction is needed due to the effect of parasitic capacitance of external parts or/and PCBs. The impedance matching network components should be decided through enough evaluation on AK1222. Typical Performance using impedance matching network with LC is below. RF Input = 600MHz, IF Output = 50MHz, LO Input = 550MHz, Output Load Resistor (Rload) = 2.2k, Vdd = 5V, Ta = 25C, LO Input Level = 0dBm. Ref.
