“…The design of phase shifters is a straightforward procedure well described in the literature [3]- [7], [10] and [11]. The required preliminary design information is contained in the general phase shifter parameters and the switching component two-state scattering parameters.…”

“…In [10] and [11], I described a five-bit phase shifter employing a discrete p-HEMT. The device operates in the whole satellite band from 10.7 to 12.75 GHz and uses a novel circuit for implementing the less significant bit.…”

“…This device occupies a relatively large area of 12 cm × 2.3 cm (27.6 cm 2 ) and is difficult for implementation in phased array antennas. This paper describes a discrete GaAs p-HEMT characterization and modeling as well as the development of a discrete four-bit phase shifter with an almost triple reduction in size (10 cm 2 ), a 1.5-dB improved insertion loss, and a 2°-averaged RMS phase error than previously reported in [10]. The application of this discrete p-HEMT in a direct quadrature phase shift keying (QPSK) modulator operating in X and Ku bands is also presented in this paper.…”

The application of a discrete pseudomorphic high electron mobility transistor (p‐HEMT) as a grounded switch allows for the development of low cost phase shifters and phase modulators operating in a Ku band. This fills the gap in the development of phase control devices comprising p‐i‐n diodes and microwave monolithic integrated circuits (MMICs). This paper describes a discrete p‐HEMT characterization and modeling in switching mode as well as the development of a low‐cost four‐bit phase shifter and direct quadrature phase shift keying (QPSK) modulator. The developed devices operate in a Ku band with parameters comparable to commercially available MMIC counterparts. Both of them are CMOS compatible and have no power consumption. The parameters of the QPSK modulator are very close to the requirements of available standards for satellite earth stations.

“…A phased array system changes its antenna beam shape by controlling the amplitude and the phase of RF signals fed into each antenna element [1], [2]. In conventional microwave circuits, phase shifters are employed for phase shifting and have advantages in size and power consumption [3], [4]. However, especially in large scale arrays, the power loss and the cost increase as the number of antenna element increases because many RF components are required such as large scale power divider, high quality RF cables, phase shifters.…”

This paper proposes an active phased array antenna (APAA) to implement high scalability. The proposed APAA consists of multiple commercial fractional-N PLL (F-PLL) Synthesizers sharing a reference signal. The phase difference control between the antenna elements can be performed independently by clock shift of LE signals to each PLL. Therefore, the phase control by commercial PLL-IC is possible without using PLL-IC having a dedicated control circuit. The proposed system is demonstrated in the C-band, realizing highly accurate phase control and beamforming property.

“…In order to significantly reduce the cost, we based our design on packaged-devices allowing surface mount-technology use; i.e., to further reduce the cost. In addition, we have selected the packaged GaAs HJ-FET devices as switches rather than the more expensive low parasitic devices such as packaged PIN diodes, or HMETs for this application [1][2][3].…”

A low profile DBS antenna is a very attractive option for RV and SUV DBS customers. However, for "on the move" services, steerable antennas would be required. Mechanical steering is commonly used, as it is inexpensive, but bulky. Low profile phased array apertures are the desired alternative. However, the required production volume is currently moderate, and still does not justify MMICs' high development expenses. Hence, we have developed a low cost 5-bit Ku-band hybrid digital phase shifter circuitry to fit today's market needs. The developed hybrid circuit design is fully based on surface mount components including the switched packaged HJ-FET devices for cost reduction. The overall loss is 3 dB ± 1.5 dB, the circuit is 30 mm 2 , and the estimated cost is only a few dollars for moderate quantities.
