Even if you haven’t used one, you’ve probably seen the numerous projects with the inexpensive RTL-SDR USB dongle. Originally designed for TV use, the dongle is a software defined radio that many have ...
Developed to help simplify VCO module designs, the UPA861TD combines the companyÕs high performance NE894 oscillator chip with its NE687 buffer chip into a single miniature package. The twin ...
Alternatively, you may want to connect its inputs and output in parallel with IC1.C to increase its drive power to the transistor test circuit. IC1.A and IC1.B together with R2, R3 and C1 form an ...
The UPA895TD twin transistor combines two NE851 NPN oscillator chips in a six-pin TD package measuring 1.2 mm x 0.8 mm. In essence, users can design two voltage-controlled oscillators (VCOs) with a ...
