Tianbao A5S simple evaluation

Preface: The Tempo A5S box to get a trial, had wanted enumeration data, the results of the degree of your mother do not know ,,,



Appearance: Really simple, 28CM22CM7CM, simple kraft paper box packaging, a positive label, machine name, official WeChat two-dimensional code, micro-blog two-dimensional code,

                              
A label on the opposite side is really simple enough,





Out of the box: As it looks, it's easy to reach
                                                                                                                                             Front light treatment, 2 antennas, back vents, 4 non-slip foot pads, and wall-hanging holes, behind are: 3 color AV output holes, 2 USB ports, wired network interface, HDML interface, power interface, The physical power switch key, the interface is quite comprehensive, supports the access to the old TV,










Remove the above box and liner, the bottom is the accessories, standard remote control, a power supply, an HDMI cable, a certificate, an AV cable




Startup articles : the front of the box is a sapphire lamp, the system into a sofa desktop, a WIN8 desktop, enter the system settings under the wireless network connection, then plug in the cable can be







Application: A5S application has a lot of built-in, common and common, TV cat, sofa butler, of course, with a sofa butler, there will be no application,









Film and TV: The film and television watched live, on demand, and it was relatively smooth.




















Games and Nominal 4K and 3D: Game features, the author did not play, 4K and 3D, did not test,


Summary: Just as the box says: In addition to ease of use, we can't promise too much. Indeed, as an ordinary TV box to use, not to pursue other aspects, or more qualified, is an entry-level standard box, the pursuit of the overall performance of the box. The overall A5S is weak.

High Frequency PCB
High frequency PCB also called HF PCB.The RF frequency range is typically from 500 MHz to 2 GHz, and designs above 100 MHz are considered RF. The microwave frequency range is anything above 2 GHz. There`s a considerable difference between RF and microwave circuits versus typical digital and analog circuits. In essence, RF signals are very high frequency analog signals. Therefore, unlike digital, at any point in time an RF signal can be at any voltage and current level between minimum and maximum limits. We have much experience in this filed,up to 60 GHz PCB we made.

1.Made of special Resin system material with Low ER and Low loss factor

2.Hybrid Build up mix of FR4 with Low loss material
3.Tight Impedance control
4.Used in Automotive, Radar, CAR to CAR communication, Distance Assistance, Active Drive Systems
We say high frequency ,also like RF PCB and Microwave PCB as they are special material too,not usual FR4 .We have Taconic,Rogers,F4B,F4BM.PTFE material in stock.With this,we can do your special boards quick turn.Unlike other suppliers need long time to purchase material.
