A UHF oscillator circuit includes a plurality of first leadless, or "chip", surface mounted components machine positioned on a first side of a printed circuit (PC) board and a plurality of second lead-bearing components mounted on a second side of the PC board and coupled in circuit through the PC board to the chip components in an arrangement which substantially reduces circuit fabrication costs. Comprised of a majority of automatically positioned surface mounted chip components and making use of a minimum number of lead mounted discrete components, the low Q values of the surface mounted components are compensated for by an external surface mounted feedback capacitor coupled across the collector-emitter junction of a common base transistor to provide oscillator tuning over a frequency range greater than an octave.
A tunable UHF oscillator circuit positioned on first and second facing sides of a printed circuit board having a plurality of apertures therein, said UHF oscillator circuit comprising:
