POWER ATTENUATORS
TYPE ATF
-
National RF’s Type ATF Power Attenuators were designed to allow interfacing of linear power amplifiers to RF exciters, where a specific amount of drive to the amplifier is prescribed. Often, however, drive from the RF exciter exceeds this minimum prescribed level and some form of power attenuation must be used in order to not damage the input of the power amplifier. National RF’s type ATF-3 offers 3 dB of power attenuation (1/2 of the power) when used between the exciter and the amplifier and will handle an input power of 132 Watts, RMS (continuous power) while providing about 66 Watts RMS output power, when it is terminated into 50 ohms. In practice, the ATF-3 attenuator will handle exciters achieving Peak Envelope Power levels (PEP) in the area of 200 to 250 Watts while providing half of that power to the load. For less attenuation requirements, the ATF-1 and ATF-2 offer 1 and 2 dB of attenuation, respectively.

Voltage Controlled Linearized Attenuators To 16 GHz
-
Pulsar's voltage controlled, PIN diode linearized attenuators are available from 0.25-16 GHz with attenuation ranges of 32 and 64 dB. Each model includes an integrated linearizer, and a driver that controls the attenuation level. This design results in transient free switching between attenuation levels as opposed to the spurious outputs that result when an attenuation value is switched either on or off by a direct digitally controlled attenuator. Transfer function is 8 dB / Volt.

RF Milliwatt Meters
Type NDB-2 and NDB-3
-
National RF’s Type NDB-2 and NDB-3 RF Milliwatt Meters are affordable pieces of test equipment for both the RF laboratory and the home experimenter. Both provide a digital reading of RF power in dB reference 1 milliwatt of power into a 50 ohm load (i.e. 0 dBm). The circuitry consists of a low noise logarithmic amplifier that drives a digital A/D converting meter circuit. The lowest power levels that can be read are about –73 dBm (approximately 40 microvolts or .00000003 milliwatts). The maximum power input should not exceed 10 milliwatts (+10 dBm or .010 watts) when inputed without attenuation. An internal attenuator is provided and described in the next section.

RF Monitor Recertification
-
The use of RF personal monitors is widespread among wireless tower climbers and technicians. This is a relatively new development of the last five years or so. Prior to that, only a few monitors were in use. These were typically models developed for use by engineers, with a host of features not needed for routine climber protection. Consequently, they were expensive and not frequently used. As safety managers have begun to require all personnel working on wireless facilities to have personal monitors among their personal protective equipment, a new generation of cost effective equipment has emerged.
