Abstract : Sample thin film resistors fabricated during the first quarter were subjected to load life, short-time-overload and temperature cycling. Temperature coefficients of resistance were measured over the 100 to 700 ohms per square resistivity range. A method of physical adjustment of capacitors was evaluated along with unadjusted control units. Capacitors were subjected to D.C. Bias measurements to assess behavior over bias range -30 to +30 volts. Circuits Engineering on the R.F. portion of the radiosonde centered on 2N3866 Transistor Oscillator as Doubler (860 to 1680 MHz), Tripler (560 to 1680 MHz) and various other means to achieve output in 1680 MHz range with required power output. Power Output and efficiencies of the various approaches are compared. (Author)
