AM3156 is a fully integrated miniature digitally tunable bandpass filter bank covering the 0.4 to 8 GHz frequency range. The device exhibits 3 filter bands each with 256 discrete tune states and a low-loss filter bypass path contained in a 10mm QFN package. AM3156 expands on our AM3152 device by integrating the inductors and DC blocking capacitors and placing it all in one easy to install chip. AM3156 is an excellent front-end for a receiver providing both low insertion loss and valuable flexibility for tuning center frequency and bandwidth. Its small size, weight, and power consumption make it an attractive choice for demanding applications requiring low SWaP components.
