Pocket SDR FE 2CH is an open-source GNSS SDR RF frontend device for Pocket SDR. The device consists of 2 CH Maxim MAX2771 ([1]) GNSS RF front-end ICs (LNA, mixer, filter, ADC, frequency synthesizer) and a Cypress EZ-USB FX2LP USB 2.0 controller ([2]) to connect to host PCs. The f

Pocket SDR FE 2CH is an open-source GNSS SDR RF frontend device for Pocket SDR. The device consists of 2 CH Maxim MAX2771 ([1]) GNSS RF front-end ICs (LNA, mixer, filter, ADC, frequency synthesizer) and a Cypress EZ-USB FX2LP USB 2.0 controller ([2]) to connect to host PCs. The front-end CH1 is dedicated for GNSS L1 band (1525 - 1610 MHz), and CH2 is for GNSS L2/L5/L6 band (1160 - 1290 MHz). The frequency of the reference oscillator (TCXO) is 24.000 MHz, and the ADC sampling frequency can be configured up to 32 MHz.
