Detailed Technical Specifications

Unmatched Frequency Coverage

With its 6GHz to 17GHz operational bandwidth, the HMC903LP3E stands out as one of the most versatile RF amplifiers in its class. This broad frequency range enables system designers to use a single amplifier across multiple bands, simplifying designs for:

• X-band (8-12GHz) radar systems
• Ku-band (12-18GHz) satellite communications
• Microwave backhaul equipment
• Electronic warfare systems

Powerful Performance Metrics

The amplifier delivers:

• 18dB typical gain with excellent flatness across the band
• 13dBm output power at 1dB compression (P1dB) for superior linearity
• 2.2dB noise figure for sensitive receiver applications
• +25dBm OIP3 for high dynamic range requirements

Efficient Power Management

The HMC903LP3E operates on a single 3.5V supply drawing just 110mA, making it suitable for portable and power-sensitive applications. The exposed pad in the 16-VFQFN package ensures excellent thermal performance even during continuous operation.
