The NANO-POLE Series is an extended range of tunable filters developed to address applications needing an extremely small surface-mount package with low power consumption. They cover a frequency range from 30 MHz to 520 MHz with 3 dB bandwidths varying from 3.5 to 10.8%. These filters have an insertion loss up to 6.5 dB, a VSWR up to 2.2:1 and an input/output impedance of 50 Ohms. The NANO-ERF trade filter require a +3.3 VCD analog and digital supply. This supply voltage must be adequately filtered as noise present on this pin will directly influence the RF signal purity.
