WebThe SDR receiver FDM-S2 is similar in many areas to the FDM-1: the casing of the FDM-S2 is a bit bigger, the interfaces and connectors are nearly identical, the same SFE experimenter boards (see below) can be used. The most important difference between FDM-S1 and FDM-S2 is the AD converter and the directly covered frequency range. WebFeb 17, 2015 · The transistor amplifier operates together with the PIN diode TX/RX switch. The schematic of the external PA and the TX/RX switch is shown in Figure 2. A low cost transistor BFP450 is used. The base of the transistor Q1 is biased from the TX/RX switch through the resistor RTX2 in transmit mode only. In receive mode the transistor is off.
