The antenna is designed to operate at 94 GHz with a few percent bandwidth. Performance, structure, and process capability of both ceramic and conductor are explained in the following pages. The stacked configuration is designed by using an equivalent circuit together with EM simulators. Overview Low Temperature Co-fired Ceramic (LTCC) is a multi-layer glass ceramic substrate, sometimes referred to as "Glass Oct 13, 2013 · Page 1 and 2: LTCC A6 system for wireless solutio Page 3 and 4: Compatible Material Systems FERRO A Page 5 and 6: Typical Processing Guidleines Lamin Page 7 and 8: FX 30-025 gold conductor paste is a The Ferro A6 was completely amorphous as an unfired tape, without the addition of a secondary alumina filler and fired as LTCC Tape 951 943 A6 CT 800 CT700 T 2000 D ! =! " The design is presented of aperture-coupled microstrip line-fed patch antennas (ACMPAs) and 4times4 planar arrays on Ferro A6-S low-temperature cofired ceramic (LTCC) substrate operating in the 60-GHz frequency band. Low dielectric constant/low loss LTCC materials have drawn much attention with the emergence of 5G wireless telecommunications. Thickness before sintering: 127 μm; Sintering shrinkage (X, Y): 15. The S21 The dielectric in Ferro A6 LTCC tape is a calcium boro-silicate, crystallizing glass. May 1, 2014 · In this paper we describe the most commonly used methods for analysis the mechanical properties of 3 types LTCC substrates (DuPont 951, DuPont 9K7, MuRata) based on three- and four-point bending LTCC is typically a glass-ceramic system, for example, A6 is a crystallizing glass in the Ca-B-Si-O system [4]. The tape is available in standard thicknesses and widths. In addition to the traditional ACMPA design, air cavities processed inside the LTCC substrate are used to improve the bandwidth and gain of the antennas. Commercially available LTCC tapes for high-frequency applications can be bought from D. 0 × 5. To enhance the crystallisation it is also common to add some nucleating agents. In addition, a low-loss LWG feed network is applied to antenna array design. 2 in [5 been fabricated on LTCC Ferro A6-M substrate with a dielectric constant of 5. 9 dBi. 22 mm, respectively. Ferro A6-S LTCC tape system with a fired tape thickness of 100 m. End-coupling capacitances between each pairof adjacent resonators defined in Figure 2 are C12 = C45 =54fFandC23 = C34 LTCC Technology has been extensively explored in the microelectronics industry as a ceramic packaging technology for integrated microcircuits. The DRO module described here was fabricated by C-MAC MicroTechnology using Ferro A6 material. The UC-EBG design is used with an aperture-coupled microstrip-line-fed patch antenna (ACMPA) and with a 16-element array to increase the antenna gain. The things that power our world and help us communicate with each other like satellites, phones and computers are made up of many materials big and small. Commercial LTCC from Ferro A6-M follows this procedure, using CaO-SiO 2-B 2 O 3 glass as a starting material, devitrifying it to wollastonite crystal surrounded by a small amount of borosilicate glass. Feb 1, 1994 · LTCC technology offers many attractive features including mechanical strength, high temperature performance, hermeticity and, with advanced crystallisable ceramic compositions, such as the Ferro A6 tape, outstanding microwave performance. The low dielectric constant and dielectric loss enable low latency devices with enhanced performance. The experimental work has been made with Du Pont 951 and Ferro A6-S LTCC systems. EN. LTCC A6 is expected to have a dynamic impact within the wireless market segment because it represents a major breakthrough for high-frequency, low-cost applications. 0015 up to 60GHz. The LTCC tape system has a low dielectric constant and low loss up to 110 GHz, making it suitable for advanced packaging applications. A wide range of materials and processes are available. The materials requirements for these applications are demanding, requiring low loss at high frequencies, Feb 27, 2018 · 这类材料以美国Ferro 公司开发的Ferro A6 为代表，其特点是材料显微结构均匀，能够实现低介电常数和较低损耗，热性能和力学性能均有保证。 其缺点是材料体系单一，不容易实现性能的调控和系列化。 LTCC Process Figure 6.
