SDRstick_48x48 SDRstickTM UDPSDR-TX2 200kHz – 55MHz Transmitter


The UDPSDR-TX2 features a 14-bit DAC clocked at up to 210Msps. The TX2 is designed to be a companion transmitter to the UDPSDR-HF2 DDC Receiver also from Zephyr Engineering, Inc and the Altera Cyclone V SoCKit board from Arrow Electronics. The TX2 transmitter, HF2 receiver, HSMCMEC-AD1 adapter and SoCKit board form a complete high-performance 200kHz – 55MHz Digital Down Conversion/Digital Up Conversion transceiver. The UDPSDR-TX2 joins the UDPSDR-HF1 (14-bits@80Msps) receiver and the UDPSDR-HF2 high performance receiver (16-bits@122.88Msps) to round out the SDRstickTM family.
