IPC: H01L29/205
Filed: 1988-08-03
Abstract: The invention relates to a microwave transistor made from III-V materials such as Ga As and Al Ga As. 
<??>This transistor essentially comprises a double heterojunction formed by a first, n-doped for example, layer (4) of material with large forbidden band, a second, undoped, layer (5) with small forbidden band, and a third, p-doped, layer (6) with large forbidden band. Under the action of the electric field of the gate (9), there may be formed simultaneously or otherwise in the second layer (5) a two-dimensional electron gas (7) at the interface with the first layer (4) and a two-dimensional hole gas (8) at the interface with the third layer (6). By adjusting the thickness (d0, d1, d2) of the layers (4, 5, 6) it is possible to symmetrise the characteristics of the n and p channels. 
<??>Applications to high-frequency electronics, in frequency doubling or complementary logic.

Inventor: RUDOLPH DIETMAR PROF DR
IPC: H04H20/36
Filed: 1989-04-15
Abstract: The invention relates to a method for digitally phase-modulating a carrier with data signals, which is based on a modified quadrature amplitude modulation method which is composed of an amplitude modulation (AM) of the carrier and a double-sideband modulation (DSB) rotated by 90 DEG . In this arrangement, the AM and the DSB are controlled in such a manner that the resultant indicator of the phase modulation maintains a constant length and the variation with time of the oscillation accurately corresponds with the modulating signal. The time functions of the AM and DSB signals are stored as reference values in EPROMs. The EPROMs are read out in dependence on the data to be transmitted in such a manner that a 90 DEG  -rotation of the DSB signal compared with the AM signal is obtained. The data are shaped and band-limited by suitable selection of the reference values in the EPROM. The modulation occurs in each case in Ex-OR switched-mode modulators which are followed by a latching element and a digital/analog converter. The outputs of the two digital/analog converters are added to the desired phase modulation signal. Interference components are removed from the signal in a subsequent band-pass filter. <IMAGE>
