1General description 1
Introduction 1.1
The BLAH100 / 900MHz (P/N:W1345047) is a linear pulse amplifier specificallydesigned for Nuclear Magnetic Resonance (NMR) applications.
It is a class AB linear amplifier and provides a 100W peak power outputs over thefrequency range 850-900MHz.
A low power output of 10W peak power over the range 850-900MHz is provided atthe 19F output.
An input is provided for the X amplifier to switch the 1H/19F/X channels to a QNPprobe.
The amplifier is realised by employing N-CHANNEL MOS BROADBAND RFPOWER FETs of the latest generation. The unit can provide full power for anycombination of pulse width of 100ms and duty cycle up 10%. Its built-in protectioncircuitry may allow lower limitations.
An electronic protection circuitry has been designed to protect against:
• Excessive power output level (overdrive)
• Excessive pulse repetition rate (over duty-cycle protection)
• Excessive pulse width (over pulse-width)
• More than 50% reflected RF power (mismatch ≥=6)
• Thermal overload (overheat)
The amplifier is powered by an internal Switched power supply assembly that pro-vides the 28VDC for the power amplifiers, in addition to all low level voltages forthe system.
The supply is auto-protected for overcurrent and overvoltage.
The entire unit is housed in a 19", 4U, 520mm rack cabinet.
System Check 1.2
Before applying power for the first time the following items should be checked :
• The AC input voltage from the Amplifier must be compatible with 176 to264 VAC range.
• External blanking ( gating ) pulses must be supplied to the amplifier at the BLKinput and with the proper level and logic polarity.
• The Amplifier has a nominal input level of +4dBm. Ensure that the system driv-ers are operating at these levels.

General description
Initial Turn On Procedure 1.3
The following list describes how to turn on the Amplifier and what should be seenas this occurs.
Before starting this procedure, make sure that you have properly followed instruc-tions in the "System Check" section.
1. Connect the amplifier to the AC line and turn the circuit breaker on the frontpanel, to ON.
2. Observe the display on the front panel :The +30V, +15V, -15V and +5V display LEDs must be lighted.
3. System is now fully operational.

Amplifiers 4.1
The BLAH100 900MHz amplifier P/N:W1345047, provides a high power outputsat nominal 100W in the frequency range of 850-900MHz.
The RF section of the system consists of a linear preamplifier of about 10W wichdrive a median stage of 40W and finaly the output push-pull of 150W.
The linear gain of the amplifier is about 50dB.
The linear amplifier is a class AB with the all stages blancked with the BlankingHigh signal on the transistor gates.
It can deliver a CW power of 25W max.
The second amplifier is a 10W push-pull in the frequency range of 850-900MHz.
The linear gain is about 38 dB.
The linear amplifier is a class AB with all stages blancked with the Blanking Medsignal on the transistor gates.
It can deliver a CW power of 10W max.
Switchs and detection 4.2
A fast pin diode switch allow to control the output witch get the 100W or the 10Wpower.(1H/19F)
A slow relais control the output witch get the X Input or the 1H/19F output. Beforegoing to the outputs the RF signals are detected in two bidirectional coplers to getan image of the output RF pulse amplitude for reflected and forward waves.
Control Board 4.3
The BLA Control Board consists of circuitry for monitoring the output power of theamplifier wich is detected in the bi-directional coupler, and to condition the inputblanking ( gating ) signals and deliver them to the amplifiers.
The monitoring is effective on overstress in peak power, average power versusduty cycle and pulse width, so as reflected power,but also for heatsink tempera-ture to protect against thermal overstress and power supplys monitoring or fansdefaults.
In case of default the gating signals are disabled, and the corresponding defaultstatus display on the front panel is on.
All these informations are also sended to the CPU via the RS485 interface.
