Ampleon BLP9G0722-20G 20W LDMOS RF Transistor

Ampleon BLP9G0722-20G 20W LDMOS RF Transistor

The Ampleon BLP9G0722-20G is a 20W-class LDMOS RF power transistor designed for broadband wireless infrastructure and RF driver applications from 100MHz to 2700MHz. Operating with a 28V drain supply under specified RF test conditions, it provides high power gain, good efficiency and integrated ESD protection.

At 1805–1880MHz, the device delivers 19dB typical gain and 21% drain efficiency at 35dBm average W-CDMA output power. The BLP9G0722-20G is supplied in a TO-270 gull-wing package, with BLP9G0722-20GZ as the complete orderable part number.

BLP9G0722-20G Key Specifications

Note: The 19dB gain and 21% efficiency values are based on the manufacturer's specified 1805–1880MHz W-CDMA application conditions. Performance changes with frequency, output power, bias and matching network.

28V Bias and RF Power Design

The BLP9G0722-20G uses a nominal 28V drain supply and a quiescent drain current of 180mA in the manufacturer's RF characterization circuits.

The typical gate voltage is approximately 2.1V at the specified quiescent operating point, but actual gate bias must be adjusted to establish the required drain current.

Engineers should verify:

• Bias sequencing: Establish the required gate bias before enabling the drain supply and follow the manufacturer's recommended startup procedure.

• RF power: Distinguish 20W nominal compression power from linear average output power under modulated signals.

• Gain: Verify gain across the target operating band using the appropriate matching network.

• Linearity: Evaluate ACPR and gain compression at the required signal bandwidth and output level.

• Thermal design: Provide an adequate thermal path from the transistor package to the PCB or heatsink.

RF Matching and Load-Pull Considerations

The BLP9G0722-20G requires external input and output matching networks. It should not be treated as a complete 50Ω matched RF amplifier module.

Ampleon provides load-pull impedance data, demonstration PCB information and simulation models for RF circuit development.

For example, the manufacturer's maximum-power load-pull data at 1840MHz gives a typical source impedance of 1.3 − j5.8Ω and a load impedance of 3.0 − j1.2Ω under the specified 28V and 180mA bias conditions.

These are device-plane matching targets under defined test conditions, not direct 50Ω port specifications. Engineers should use the appropriate matching and reference-plane definitions when designing the amplifier.

BLP9G0722-20G vs BLP9G0722-20

Ampleon has discontinued the earlier BLP9G0722-20 and identifies the BLP9G0722-20G as its replacement.

Before replacing the discontinued version, compare the latest mechanical drawings, lead geometry, PCB footprint, grounding and RF matching requirements.

The manufacturer's replacement recommendation does not eliminate the need for application-specific compatibility verification.
