DESIGN CONSIDERATIONS MRF134 power N-Channel enhancement mode field-effect transistor (FET) designed especially power amplifier oscillator applications. Motorola FETs feature vertical structure with planar design, thus avoiding processing difficulties associated with V-groove vertical power FETs. Motorola Application Note AN-211A, FETs Theory Practice, suggested reading those familiar with construction characteristics FETs. major advantages power FETs include high gain, noise, simple bias systems, relative immunity from thermal runaway, ability withstand severely mismatched loads without suffering damage. Power output varied over wide range with power control signal, thus facilitating manual gain control, modulation. BIAS MRF134 enhancement mode and, therefore, does conduct when drain voltage applied. Drain current flows when positive voltage applied gate. Figure typical plot drain current versus gate voltage. power FETs require forward bias optimum performance. value quiescent drain current (IDQ) critical many applications. MRF134 characterized which suggested minimum value IDQ. special applications such linear amplification, have selected optimize critical parameters. gate open circuit draws current. Therefore, gate bias circuit generally just simple resistive divider network. Some special applications require more elaborate bias system.
GAIN CONTROL Power output MRF134 controlled from rated value down zero (negative gain) varying gate voltage. This feature facilitates design manual gain control, AGC/ALC modulation systems. (See Figure
AMPLIFIER DESIGN Impedance matching networks similar those used with bipolar transistors suitable MRF134. Motorola Application Note AN721, Impedance Matching Networks Applied Power Transistors. higher input impedance FETs helps ease task broadband network design. Both small signal scattering parameters large signal impedances provided. While s-parameters will produce exact design solution high power operation, they yield good first approximation. This additional advantage power FETs. power FETs triode devices and, therefore, unilateral. This, coupled with very high gain MRF134, yields device capable self oscillation. Stability achieved techniques such drain loading, input shunt resistive loading, output input feedback. MRF134 characterized with 68-ohm input shunt loading resistor. port parameter stability analysis with MRF134 s-parameters provides useful-tool selection loading feedback circuitry assure stable operation. Motorola Application Note AN215A discussion port network theory stability. Input resistive loading feasible noise applications. MRF134 noise figure data generated circuit with drain loading loss input network.
