This paper presents a groundbreaking Ku-band 20W RF front-end power amplifier (PA), designed to address numerous challenges encountered by satellite communication systems, including those pertaining to stability, linearity, cost, and size. The manuscript commences with an exhaustive discussion of system design and operational principles, emphasizing the intricacies of low-noise amplification, and incorporating key considerations such as noise factors, stability analysis, gain, and gain flatness. Subsequently, an in-depth study is conducted on various components of the RF chain, including the pre-amplification module, driver-amplification module, and final-stage amplification module. The holistic design extends to the inclusion of the display and control unit, featuring the power-control module, monitoring module, and overall layout design of the PA. It is meticulously tailored to meet the specific demands of satellite communication. Following this, a thorough exploration of electromagnetic simulation and measurement results ensues, providing validation for the precision and reliability of the proposed design. Finally, the feasibility of that design is substantiated through systematic system design, prototype production, and exhaustive experimental testing. It is noteworthy that, in the space-simulation environmental test, emphasis is placed on the excellent performance of the Star Ku-band PA within the 13.75GHz to 14.5GHz frequency range. Detailed power scan measurements reveal a P1dB of 43dBm, maintaining output power flatness < ± 0.5dBm across the entire frequency and temperature spectrum. Third-order intermodulation scan measurements indicate a third-order intermodulation of ≤ -23dBc. Detailed results of power monitoring demonstrate a range from +18dBm to +54dBm. Scans of spurious suppression and harmonic suppression, meanwhile, show that the PA evinces spurious suppression ≤ -65dBc and harmonic suppression ≤ -60dBc. Rigorous phase-scan measurements exhibit a phase-shift adjustment range of 0° to 360°, with a step of 5.625°, and a phase-shift accuracy of 0.5dB. Detailed data from gain-scan measurements show a gain-adjustment range of 0dB to 30dB, with a gain flatness of ± 0.5dB. Attenuation error is ≤ 1%. These test parameters perfectly align with the practical application requirements of the technical specifications. When compared to existing Ku-band PAs, our design reflects a deeper consideration of specific requirements in satellite communication, ensuring its outstanding performance and uniqueness. This PA features good stability, high linearity, low cost, and compact modularity, ensuring continuous and stable power output. These features position the proposed system as a leader within the market. Successful orbital deployment not only validates its operational stability; it also makes a significant contribution to the advancement of China’s satellite PA technology, generating positive socio-economic benefits.

“…It was mentioned earlier that the gate noise is related to the drain noise. In fact, it is partially correlated to the drain noise, with a correlation coefficient c, stated as in equation 5- [5] The value for c is given as 0.395j for long channel devices. The purely capacitive nature of the correlation coefficient is due to the fact that the coupling between the gate noise and drain noise is through the gate capacitance.…”

Low Noise Amplifier (LNA) is the most critical part of a receiver front end in terms of the receiver performance. The performance tradeoff among input matching, noise figure, gain, and linearity are analyzed in detail. The LNA finds its application at Portable GPS Receiver, BLE, Zigbee, NFC, WiFi, Wireless Sensor Network, RFIC operating at 2.4GHz frequency. Millimeter wave communication is an evolving technology for bandwidth demanding 5G wireless application. A high gain and linear narrowband cascode Low Noise Amplifier (LNA) operating at 2.18GHz to 2.47GHz is proposed. To demonstrate design methodology, a narrow-band source degenerated cascode LNA is designed and simulated in a standard 90nm CMOS process to operate in the 2.4 GHZ band. The LNA achieves a voltage gain of 5.38dB, Noise figure of 4.1127dB, and from 3.2 V supply voltage. Proper input and output impedance matching have been performed to achieve the input return loss of -14 dB (S11) and output return loss of -19.72 dB (S22). Simulation study has been done using Cadence spectre.

A 28 GHz two stage low noise amplifier (LNA) is proposed with envelope detection technique for power reduction (21.62%) and tunable negative feedback capacitor for gain variation in 40 nm CMOS technology. The envelope detection circuit turn‐on the second half of the LNA by the RF signal input received at the first stage. The default gain is increased (31.53%) by the tunable negative feedback capacitor circuit of the LNA with the control voltage from 0 to 1 V. In addition, 6.22 GHz of bandwidth is achieved with the tunable gain from 20.3 dB to 26.7 dB. The first stage of the LNA is designed with the inductive source degeneration for the noise reduction, and the multiple‐gate topology is involved in the second stage to improve the linearity. The third‐order input intercept point and the noise figure of the LNA are −7 dBm and 2.86 dB, respectively. When the second stage is turned‐on and turned‐off the LNA consumes 7.4 mW and 5.8 mW of power, respectively, from the 1 V supply. The proposed LNA requires 0.19 mm2 of core area. The performance of the LNA under process corner variation and temperature variation are analyzed.
