This paper presents the evaluation and analysis of two multi-band, transceiver architectures that address the current demands in telemetry applications. One architecture used image rejection to perform coarse band selection, translating the RF spectrum to IF frequencies, while the second architecture utilizes an adaptive filter bank architecture for more agile band selectivity. Both architectures consist of an analog front-end subsystem for signal conditioning and frequency translation, and a digital radio subsystem for band and channel selection. The transceiver prototype was designed to operate over the L-band 1435-1535 MHz, S-Band 2200-2295 MHz, 2310-2385 MHz, and C-Band 4400-4950 MHz, 5091-5250 MHz. System block-diagrams, simulations and measured results with a comparison between the two architectures, are presented.
