A low loss reflection-type analog phase shifter circuit producing a large range (nearly 360°) of phase shift at X-band while achieving low attenuation (insertion loss) and little amplitude variation over all ph
The designed and measured device was capable of full 360° degree phase shift with lower losses than reported for analog DMTL phase shifters. The full phase shift was achieved at 14.6 GHz with a 1.9 dB insertion loss. The achieved figure of merit (FOM) for the device was 188°/dB. ...

The SPI communication was used to control the digital phase shifters and attenuators, while the output voltage of the RF power detector was read through the analog-to-digital converter (ADC). The test configuration is shown in Fig. 8 (b), where the distance between the PAA under calibration...
A novel optical injection locking amplifier with acousto-optic modulator based phase modulation and a coherent detection scheme for optical frequency transfer applications is experimentally demonstrated in this study. A commercial distributed feedback diode laser is injection-locked to the resonant frequency...
A dual-band electromagnetic band gap (EBG) electronically scanned antenna utilizing frequency selective surfaces (FSS) uses FSS waveguide phase shifters. Each FSS waveguide phase sh
low in-band insertion loss (IL). In one embodiment, the composition and geometry of distributed elements, such as tapered conductive line404, first resistive film410, second resistive film412, third resistive film424and fourth resistive film426, extend a high-frequency end of a stop band while...
Low inductor core loss is evidenced by reduced no-load input current and higher light-load efficiency. However, ferrite core materials exhibit a hard saturation characteristic and the inductance collapses abruptly when the saturation current is exceeded. This results in an abrupt increase in inductor ...
This indicates the loss of lock of the PLL and this is cleared only by recalibration or a hard reset through RESETN/ SYNC pin 0h = locked 1h = unlocked 0 lock_det R 0h When the calibration is done frequency may or may not be locked. 1h = Frequency is locked. 0h = Otherwise 0h...
