“…Practical solutions must not only meet the electrical specifications but also be compact and immune to microphonic effects and thermal fluctuations. A wideband receiver module was designed to meet these requirements and to provide matching phase and amplitude [2]. A wideband receiver that is located next to an antenna requires low noise figures (NFs) because very low input signals are received by the antenna.…”

This paper proposes the design and measurement of a 6-18 GHz front-end receiver module that has been combined into a one-channel output from a two-channel input for electronic warfare support measures (ESM) applications. This module includes a limiter, high-pass filter (HPF), power combiner, equalizer and amplifier. This paper focuses on the design aspects of reducing the noise figure (NF) and matching the phase and amplitude. The NF, linear equalizer, power divider, and HPF were considered in the design. A broadband receiver based on a combined configuration used to obtain low NF. We verify that our receiver module improves the noise figure by as much as 0.78 dB over measured data with a maximum of 5.54 dB over a 6-18 GHz bandwidth; the difference value of phase matching is within 7° between ports.

“…In addition, each component is connected using a microstrip line or a short RF cable for fabrication and testing. Additional tuning is also required to reduce mutual mismatching [2][3][4]. As previously discussed, the broadband switching matrix module connected to the rear end of the antenna in the electronic support equipment system is a key element determining the overall system performance.…”

In this paper, we design and fabricate a broadband switching matrix box with low-noise figure, flat gain characteristics, and reliability by applying the chip-and-wire process using a bare-type MMIC device. To compensate for the mismatch among many components, the limiter, switch, amplifier, and power divider, which are suitable for sub-band frequency characteristics, are designed and applied to the matrix box. The matrix box has three submodules that are phase-matched for each frequency band and one built-in test (BIT) submodule to select the BIT path for calibration. Phase-matched RF semi-rigid cables of different lengths are used to connect to the external interface of the matrix box. The main RF line is a dielectric substrate, RT/Duroid 5880, with a relative dielectric constant of 2.2 and a dielectric thickness of 0.127 mm. The BIT path is a dielectric substrate, ceramic alumina (AI2O3), which has a relative dielectric constant of 9.8 and a dielectric thickness of 0.254 mm. In the wideband switching matrix box, the gain is from −1.71 dB to −2.69 dB at LB (input frequency, 0.5−2 GHz), with a flatness of 1.0 dB. Th e gain is from +14.8 dB to +12.4 dB at MB (input frequency, 1−6 GHz), with a flatness of 2.4 dB. The gain is from +12.6 dB to +9.4 dB at HB (input frequency, 6−18 GHz), with a flatness of 3.2 dB. The measured values of the noise figure are 2.69 dB at low band, 4.4 dB at medium band, and 5.95 dB at high band with a maximum value. The measured value of phase matching at high band is 7º with a maximum value.

“…As currently existing wideband receivers made of single modules can only receive signals in bands up to 2-18 GHz, they are insufficient for high-frequency signals in millimeter-wave bands. In addition, as the local oscillator (LO) necessary for frequency conversion is not implemented in their receiver modules [7], but provided separately with converted frequencies from ES system devices, the phase noise characteristics of the entire receivers are dependent on the performance of other devices, and the size of the entire system increases owing to the separate LO module.…”

“…First, the ultra-wideband input frequency range of 18-40 GHz were divided into two bands using 18-26 GHz (Band A) and 26-40 GHz (Band B) band pass filters and these were applied to the frequency mixer input. The designed frequency spectra were such that there was no secondary harmonic component in each band, thereby preventing spurious signals from appearing in the intermediate frequencies (IF,(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18).…”

In this study, we propose an approach for the design and satisfy the requirements of the fabrication of a small, lightweight, reliable, and stable ultra-wideband receiver for millimeter-wave bands and the contents of the approach. In this paper, we designed and fabricated a stable receiver with having low noise figure, flat gain characteristics, and low noise characteristics, suitable for millimeter-wave bands. The method uses the chip-and-wire process for the assembly and operation of a bare MMIC device. In order to compensate for the mismatch between the components used in the receiver, an amplifier, mixer, multiplier, and filter suitable for wideband frequency characteristics were designed and applied to the receiver. To improve the low frequency and narrow bandwidth of existing products, mathematical modeling of the wideband receiver was performed and based on this spurious signals generated from complex local oscillation signals were designed so as not to affect the RF path. In the ultra-wideband receiver, the gain was between 22.2 dB and 28.5 dB at Band A (input frequency, 18-26 GHz) with a flatness of approximately 6.3 dB, while the gain was between 21.9 dB and 26.0 dB at Band B (input frequency, 26-40 GHz) with a flatness of approximately 4.1 dB. The measured value of the noise figure at Band A was 7.92 dB and the maximum value of noise figure, measured at Band B was 8.58 dB. The leakage signal of the local oscillator (LO) was-97.3 dBm and-90 dBm at the 33 GHz and 44 GHz path, respectively. Measurement was made at the 15 GHz IF output of band A (LO, 33 GHz) and the suppression characteristic obtained through the measurement was approximately 30 dBc.
