The XU200 is a UHF broadcasting band power amplifier with a frequency range of 470-862MHz and typical gain of 58.7dB. It has a maximum VSWR of 3:1 and operates in a temperature range of -5 to +45C. Key features include full UHF band coverage, high power output for best MER, and protection circuits. Intended for DVB-T transmission systems, it provides 200W of RF power with high linearity.
The LM380 is a power audio amplifier for consumer application. In order to hold system cost to a minimum, gain is internally fixed at 34 dB. A unique input stage allows inputs to be ground referenced. The output is automatically self centering to one half the supply voltage.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Integration and important Operating instructions
The XU200 is designed for operation up to 200Wrms (DVB signal) with very high linearity,
This design uses 6th generation family LDMOS devices that are capable of very high peak power as
long as the average power does not exceed specified ratings. The devices are protected by an
internal circuit, for Overdrive and high Mismatch load.
However is mandatory to handle with care the Input level during the "precorrection operations" due to
possible very fast and high spikes coming from the source.
The XU200 must allow the nominal voltage before applying RF driver signal or damage can result
to the amplifier. For this reason the voltage must be applied before the RF driver signal. Additionally,
the input signal, must be removed before powering down to prevent damage to the amplifier. You can
accomplish this by removing the RF driver signal and powering down the power amplifier.
The XU200 has an internal Power Supply.
When the XU200 in installed in a 19 Inch std Rack is important to leave a right space on the rear
zone to facilitate the exhausted air extraction.
It's suggested to leave one free unit (1 HE) at the top of the Amplifier.
In case of use of more XU200 in parallel an appropriate power combiner has to be used. The
connection between the Amplifiers and Power Combiner Input Ports is strongly reccomended to
use"low Loss Cables" type.
The Amplifier is equipped with an RF Monitor Output available by a SMA connector where is possible
to test the performances when the it's on duty. The RF Monitor Output is normally > -40 dB referred
to the main output in order to have a right signal managed by std Instrumentation.
The logic control unit, designed specifically for this product line, accepts all necessary interfaces
in every environment (TCP/IP, SNMP and RS485) for maximum flexibility.
The XU200 is equipped with an RS232 on the raer panel to manage and control an external
DVB-T Modulator.
