Vytek TRM-1 PRD 3 Technical Brief Scope The scope of this PRD is to describe the technical implementation of a custom modular Low-Band RF Power Amplifier Unit. The PA is part of a wide-area data network base station. It is non-linear, with redundancy built-in for extra reliability and up-time. Functionality The amplifier takes in a constant-envelope (CE) RF signal at a level of approximately 5dBm, and amplifies it to a level of 56dBm (400 watts). The amplifier module and the power supplies are all fully redundant. A CPU monitors the amplifier, manages alarms, and controls the switching of redundant circuits. The internal CPU provides a Command Line Interface (CLI) via an RS-232 serial port, for an external device to monitor and control its operation. The Amplifier runs off of 90-130V AC input. The CPU controller will also operate off of an external DC input, if available. Design Philosophy Robustness The design will incorporate, to the extent feasible and cost effective, margin against the specified criteria. In each case the margin is determined from the expected normal variations in manufacturing parameters and device variations as they apply to the design. Additionally, the product incorporates robust circuit design to require minimal alignment or tuning during test. To the extent possible, all components will be surface mount and utilize multiple source parts. The amplifier must self-protect against all fault conditions. In particular, care is taken to prevent damage due to: 1. Reverse DC voltage 2. RF overdrive 3. High VSWR on output 4. Over-temperature 5. Failure of any LRU Implementation and Construction The amplifier is divided into these sections, each section capable of being tested by itself. 1. Two field replaceable 500 watt RF Amplifier Modules. 2. An RF switch to select which output stage is routed to the antenna. 3. Lowpass Filter and RF wattmeter with directional coupler. 4. DC monitoring (current and voltage) 5. CPU Controller (bias voltage generation, AGC management, monitoring, CLI, alarming…) 6. Two field replaceable AC power supplies.

Vytek TRM-1 PRD 15 Power Supply Alarms In addition to the power amplifier alarms, Status information for both PS #1 and PS #2 is read via a 2 byte (16-bit) status word called PSStatusWord16, as described below. The amplifier sets the bit when the relevant condition occurs. The bit will stay set until cleared by a write of a 0 to the corresponding bit in the status register. “Push” Enabling for alarm conditions The TRM-1 can be configured to send unsolicited alarm information (see command table below) on the occurrence of a power amplifier or power supply alarm. The unsolicited alarm information is sent as PAStatusWord24 or PSStatusWord16 through the serial port. It is sent once on the setting of any alarm bits in Byte 2 or Byte 3 of PAStatusWord24, or if a Power Supply alarm occurs, Byte 1 or Byte 2 in PSStatusWord16. The pushed alarm status word will be sent in ASCII format (as are all commands and responses). It will have the following format. Note that numeric values are given in hex. PAStatusWord24=488000 or PSStatusWord16=0400 By default, alarm “push” is enabled.

In each case the margin is determined from the expected normal variations in manufacturing parameters and device variations as they apply to the design. Additionally, the product incorporates robust circuit design to require minimal alignment or tuning during test. To the extent possible, all components will be surface mount and utilize multiple source parts. The amplifier must self-protect against all fault conditions. In particular, care is taken to prevent damage due to: Reverse DC voltage RF overdrive High VSWR on output Over-temperature Failure of any LRU Implementation and Construction The amplifier is divided into these sections, each section capable of being tested by itself. 500 watt RF Output Stage. A two-stage power module, field replicable, with approximately 25dB of gain. Two per unit. RF Driver/Splitter/AGC Stage. With approximately 20dB of gain. One per unit. RF switch to select which output stage to operate off of. RF wattmeter with directional coupler. DC monitoring (current and voltage) CPU Controller (bias voltage generation, AGC management, monitoring, CLI, alarming…)
AC power supply, two per unit. Load-sharing, each with enough capacity to output 1500 watts if needed. Operation The amplifier should look like a gain block, with some AGC for power leveling. It powers up in the “on” state. Status Word Definition Status byte For all bits except bit 6, the amplifier sets the bit when the relevant condition occurs. The bit will stay set until cleared by a write of a 1 to the corresponding bit in the control register. Bit 6 indicates whether the amplifier is active or shut down. The amplifier may only be brought back online by writing a 1 to bit 6 of the status byte, but shutdown may occur either by writing a 0 to bit 6 of the status byte, or by one of the shutdown conditions being detected. 7 6 5 4 3 2 1 0 Fan Warn Flag Amp Online Amplifier Reset Flag Active Amp Overdrive Warn Flag Thermal Warn Flag Overdrive Shutdown Flag Thermal Shutdown Flag
