Typical Applications
ADPA1112 is suitable for 6 applications: Radar Systems, Electronic Warfare (EW), Satellite Communications (SATCOM), Test and Measurement, 5G and Broadband Communication, Software-Defined Radio (SDR).
Radar Systems
The ADPA1112's wideband coverage from 1 GHz to 22 GHz makes it ideal for multi-band radar transmitters. Its 42 dBm saturated output power provides the necessary drive for long-range detection, while the GaN technology ensures high efficiency and reliability in pulsed operation. The amplifier can be used in both military and civilian radar systems, including weather radar and air traffic control, where frequency agility is required to avoid interference and improve target resolution.
Recommended
Electronic Warfare (EW)
In electronic warfare, the ADPA1112 is used in jamming and countermeasure systems that require wideband frequency coverage to disrupt enemy communications and radar. Its 1-22 GHz range allows a single amplifier to cover multiple threat bands, simplifying system design. The high output power of 42 dBm ensures effective jamming, while the 25% PAE helps manage thermal loads in compact EW pods. The amplifier's fast switching capability supports frequency hopping and agile waveforms.
Recommended
Satellite Communications (SATCOM)
The ADPA1112 is suitable for SATCOM uplink and downlink amplifiers operating in C, X, Ku, and K bands. Its wideband nature allows a single design to support multiple satellite frequency bands, reducing inventory and development costs. The 42 dBm output power meets the requirements for ground terminals and VSAT systems, while the GaN technology provides the linearity needed for high-order modulation schemes. The amplifier's 50-ohm matched input and output simplify integration with antennas and transceivers.
Recommended
Test and Measurement
In test and measurement equipment, the ADPA1112 is used as a broadband driver amplifier for signal generators, spectrum analyzers, and network analyzers. Its 1-22 GHz frequency range covers most RF test requirements, eliminating the need for multiple narrowband amplifiers. The high output power allows testing of high-power devices and systems, while the flat gain response ensures accurate measurements across the band. The amplifier's rugged GaN design withstands mismatched loads and overdrive conditions common in test environments.
Recommended
5G and Broadband Communication
The ADPA1112 can be used in 5G base stations and broadband communication systems that require wideband amplification for carrier aggregation and multi-band operation. Its 1-22 GHz range covers sub-6 GHz and mmWave bands, making it a versatile choice for future-proof designs. The 42 dBm output power supports high-capacity links, while the 25% PAE reduces power consumption and cooling requirements. The amplifier's linearity is sufficient for QAM modulation schemes when operated with appropriate back-off.
Recommended
Software-Defined Radio (SDR)
The ADPA1112 is ideal for software-defined radio transmitters that need to cover multiple frequency bands with a single hardware platform. Its 1-22 GHz bandwidth allows an SDR to operate from HF to K band, enabling flexible and reconfigurable communication systems. The high output power ensures adequate signal strength for long-range links, while the GaN technology provides the efficiency needed for portable and battery-operated SDRs. The amplifier's wideband performance simplifies the RF front-end design, reducing component count and cost.

Key Differentiators
- Wideband frequency coverage from 1 to 22 GHz (vs ADPA1122)
- High output power of 42 dBm (vs TGA2594-SM)
- GaN technology for high efficiency (vs MAAP-011319)
Design Notes
The ADPA1112 dissipates significant heat at 42 dBm output power. Ensure adequate thermal management by using a heatsink or thermal vias under the exposed pad. The LDCC package has a thermal resistance that must be considered; refer to the datasheet for theta_JA and design accordingly to keep junction temperature below the maximum rating.
Use high-frequency PCB materials such as Rogers or PTFE for the RF traces. Keep input and output traces as short as possible and maintain 50-ohm impedance. Place decoupling capacitors close to the bias pins to minimize power supply noise and ensure stable operation.
Do not exceed the maximum drain voltage or input power ratings. Ensure proper bias sequencing: apply gate bias before drain bias to prevent damage. Use a current-limiting power supply during initial testing to avoid overcurrent conditions.
