2.3 HEAT SINKING

The NuPower S100A01 is offered as a stand-alone module or with an optional heat sink

(p/n: HTSK-07), which includes a 28 VDC fan-cooled heatsink and requisite power cable.

Caution: The use of external heat-sinking is required especially for those applications

requiring high duty cycle operation (e.g. continuous wave) or for extended on-time testing.

Operation without a proper heat sink under these conditions will cause permanent damage

to the product and will void the product warranty.

The maximum operating temperature of the module only is 70˚ C (baseplate).

3SETUP AND OPERATION

This section provides specific details for proper operation of the NuPower S100A01 module. Following

these guidelines will prevent damage to the power amplifier or external equipment.

3.1 POWER SUPPLY REQUIREMENTS

To operate the NuPower S100A01, ensure that the power supply has adequate overhead to source the

current demand of the RF power amplifier. The power supply source must provide a typical voltage of

+28 VDC with greater than 13 amps capability.

3.2 CONNECTING A PROPER LOAD TO THE ANTENNA TERMINAL

To prevent damage to the PA, the antenna terminal must be terminated into a 50 Ω load. Examples of a

proper load include:

•Directly connecting to an antenna specified for the frequency range (2000 MHz to 2500 MHz).

Connecting to an inappropriate antenna may result in damage to the PA module.

•Connecting to a proper antenna through a 50Ω transmission line or coaxial cable. Avoid using

damaged cables or corroded connectors while attaching the unit to an antenna.

•Terminating the antenna terminal into a 50Ωhigh power attenuator with minimum 20 dB

attenuation.

•Connecting to a load capable of dissipating the RF power from the PA module. Loads capable of

handling 200 Watts (min) are recommended.

3.3 POWERING-UP THE NUPOWER S100A01

The NuPower S100A01 must be terminated to a proper load before power is applied. Refer to Section

3.2 for the specifications of the proper load. After the PA is properly terminated, the interface cable can

be connected to the unit and power can be applied. The PA is now ready for operation.

3.4 TRANSMIT TURN-ON TIME

The NuPower S100A01 is at full power approximately 500ns after the RF Enable line goes low (ground).

Therefore, transmit data can be applied to the input after 500ns without loss of data.

4HARDWARE INTERFACE

•The RF Input connector is SMA (female).

•The RF Output connector is SMA (female).

•The pin-out definitions for the Micro-D Hybrid, 7 +2-pin socket connector are provided in Table

5. In a typical installation, the PA module is mated to a host controller board via a cable harness.

The RF Out SMA

connector is the antenna connection. This connection should

always be loaded into 50 Ω, otherwise the PA could be damaged.

4.1 INTERFACE CABLE HARNESS

The cable harness that connects the host controller to the Micro-D Hybrid, 7 +2-pin socket connector of

the NuPower S100A01 is made up of 9 wires.

*Do not connect the Temperature Flag to DC Power (+28 Volts input). The Temperature Flag can be used

to monitor thermal status.

4.2 DC POWER

The nominal supply voltage for the NuPower S100A01 is +28 VDC. The acceptable supply voltage range

is +26 to +32 VDC. If a voltage above 32VDC is applied, the drain bias to internal amplifiers will be

removed and the transmit path will be non-operational.

4.3 GROUND

The signal and power grounds are tied together in the PA module.

4.4 RF ENABLE

This signal is the logic control input that designates whether the unit is in transmit or standby mode. The

RF Enable line is pulled high internally placing the PA module in standby mode. If the pin is left floating

(i.e. not connected), the unit will default to standby mode.

Grounding the pin (i.e. a voltage below +0.8 VDC) places the unit in transmit mode. The user can either

connect the RF Enable line to pins A1 or 3 on the CTRL/PWR interface connector, or an open drain logic

line capable of sinking 500 µA to place the unit in transmit mode.

Do not connect the RF Enable line to DC Power (+28 Volts input). No input voltage is required on the RF

Enable line.

4.5 TEMP FLAG

This signal is an output to indicate an over-temperature condition in the NuPower S100A01. A logic high

(+5 VDC) indicates normal operation, while a logic low (0 VDC) indicates an over-temperature condition.

The NuPower S100A01 incorporates internal logic circuitry that turns off the DC bias to the RF

amplifiers. See section 4.6 for details on thermal shutdown points.

Caution: The amplifier should be shut down and allowed to cool off when the over-

temperature flag is set low to avoid damage to the module.

Do not connect the Temperature Flag to DC Power (+28 Volts input). The Temperature Flag

can be used to monitor thermal status.

4.6 CURRENT TEMP

This signal is an output to indicate internal temperature of the S100A01. Temperature Flag (Section 4.5)

threshold is reached when internal temperature of approximately 85°C is exceeded and will re-enable

bias to internal RF amplifiers at approximately 70°C. See Figure 5 below for ‘current temp’ voltage and

corresponding internal temperature.
