Description
Technical field
The present invention relates to temperature detection, and in particular to power amplifier temperature detecting system.
Background technology
From 1974, the Plessey companies in the U.S. were by the use of GaAs FET as active device, and GaAs SI-substrates are as load
Body, since succeeding in developing first piece of mmic amplifier in the world, in Military Application (including intellectual weapon, radar, communication and electronics
War etc.) promotion under, MMIC development is very rapid.The eighties, with molecular beam epitaxy, metalorganic chemical vapor
The development and progress of deposition technology (MOCVD) and deep-submicron process technology, MMIC are quickly grown.1980 by Thomson-
CSF and the company's laboratory developments of Fujitsu two go out HEMT (HEMT), have been obtained on material structure constantly
Breakthrough and innovation.It is counterfeit made of the more preferable InGaAs raceway grooves of Maselink performances in 1985 to match somebody with somebody HEMT (PHEMT), make HEMT
Develop to more frequency modulation rate more low noise direction.After HEMT, substitute silicon bipolar transistor with GaAlAs/GaAs hetero-junctions within 1984
P-N junction in pipe, frequency characteristic and the more excellent heterojunction bipolar transistor (HBT) and HBT of speed characteristics are succeeded in developing
MMIC.Because InP materials have the Lattice Matching of high saturated electrons mobility, high breakdown electric field, good thermal conductivity, InP-base
HEMT, its performance is more more superior than GaAs base, and the preparation recently as InP monocrystalline makes progress, the HEMT of InP-base,
PHEMT, MMIC performance are also greatly improved.
Using triode current control effect or FET voltage control action by the power of power supply be converted to by
According to the electric current of input signal change.Because sound is the ripple of various amplitude and different frequency, i.e. AC signal current, triode
Collector current is β times of base current forever, and β is the exchange multiplication factor of triode, using this point, if small-signal is noted
Enter base stage, then the electric current that colelctor electrode flows through can be equal to β times of base current, then isolate this signal with capacitance
Come, just obtained the big signal that electric current (or voltage) is original β times, this phenomenon turns into the amplification of triode.By not
Disconnected Current amplifier, just completes power amplification.
The radiating of power amplifier, which is always one, to be needed to solve the problems, such as, the radiating mode needed for different power amplifiers is also different,
But the measurement of temperature and a critically important part, and the temperature of each part of power amplifier is different from, Suo Youxu
Separately measurement.
