This paper proposes a reconfigurable two-way wideband active power divider/combiner based on bi-directional amplifier and absorptive series-shunt switch techniques. A multi-octave operational bandwidth and flat gain response with bi-directional operation are simultaneously achieved using bidirectional distributed amplifiers (BDAs). The reconfigurable functionality and fast mode selection are obtained by using the absorptive series-shunt switches. The proposed power divider/combiner provides four different operational states depending on the control inputs for the BDAs and the series-shunt switches. The dual-path mode supports both divider and combiner operations, and the measured gain is greater than 7.8 dB and the isolation between output ports is better than 23 dB over the 3-dB bandwidth of 2-23 GHz. The measured noise figure (NF) of the dual-path mode is below 10 dB, while maximum amplitude and phase imbalances are 0.2 dB and 1.8 degrees, respectively. The single-path mode shows a measured gain of > 7.8 dB, and a port-to-port isolation > 35 dB. The measured NF is below 12 dB from 8 to 26 GHz. In addition, the proposed circuit shows the maximum output 1-dB compression point (OP1dB) of 4.6 dBm, and good matching characteristics, with a DC power consumption of 120 mW. The chip area of the reconfigurable two-way SiGe bi-directional active power divider/combiner is 1.43 mm × 0.92 mm.

5.8 GHz band digital phase shifters to control a 2. Configuration beam direction for an Active Integrated Phased Array Antenna are designed. The 4-bit phase shifters with integrated GaAs Experimental data for the high performance the FET SPDT switches are integrated with an LTCC substrate. integrated GaAs FET SPDT switches with LTCC phase We realized a low loss 4-bit LTCC phase shifter with the size shifters were obtained. The AIA array consists of an of 10 mm x 13 mm x 0.55 mm. From the simulation results, the insertion loss of LTCC phase shifter without the switch is antenna part and a circuit part (the phase shifter and simulated with about 0.5dB/bit. The insertion loss of the driver / power amplifier circuits). In order to achieve LTCC phase shifter integrated with the GaAs FET SPDT stable operation condition as well as compactness, a switches and phase error are measured to be about 2.3dB/bit created circuit substrate method was developed for the and less than 15°, respectively. multi-stage high power amplifier. The operating Key words AIPAA, an LTCC Phase Shifter, an SPDT Switch frequency of the AIA is 5.8GHz. 1. Instruction 2.1 LTCC Commercially available phase shifters are usually Recent development on telecommunication systems expensive and bulky. A substrate with complex enables us to realize a high performance active phased micro-strip lines circuit fabricate by the LTCCarray antenna (APAA) system with low cost, technology are stratified in thin multi-layers and can be multifunction, and precise beam control in a field of a small size. It is therefore our goal to build a phase shifter mobile communication system. In order to meet the that occupies less space with satisfactory performance.
