Working Principle

The LTP5903CEN-WHRB4B1#PBF is based on a two-stage RF power amplifier (PA) architecture that employs a heterodyne approach. Additionally, it incorporates an active bias network for supply voltage optimization. The first stage consists of two transistors in a common source configuration. The second stage is composed of a single transistor in a common base configuration. The PA\'s overall gain is determined by the effects of the transistor\'s intrinsic losses and output return loss. It is also controlled by the biasing voltages provided.

The amplifier\'s performance is further improved by an active bias network, which utilizes an external programmable resistor, or trim resistor. This trim resistor allows for precise impedance matching and power management, resulting in increased output power and efficiency across a wide range of frequencies. The amplifier\'s gain is also optimized over a wide range of operating conditions, since it operates with a constant RF signal drive and a voltage-variable output power. Additionally, the amplifier can be tuned to account for the effects of temperature and process shifts, resulting in high stability and reliability.
