# Industrial Specification: RF Transmitter Module

## 1. Technical Definition
Electronic component that generates and transmits radio frequency signals for wireless communication.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **2.4-2.4835 GHz, 10-20 dBm output power, -40°C to +85°C ambient temperature**. Failure boundary: **Power amplifier junction temperature exceeding 150°C, VSWR exceeding 2.0:1, local oscillator phase noise degradation beyond -110 dBc/Hz at 10 kHz offset**, Mechanism: **Thermal runaway in GaAs HEMT power transistors due to positive temperature coefficient of drain current, dielectric breakdown in RF matching networks at electric field strengths exceeding 3 MV/m, phase-locked loop instability from varactor diode capacitance nonlinearity**.

### 2.1 Analytical Physics Model
