BLA6G1011-200R,112

Overview

The BLA6G1011-200R is a 200 W LDMOS power transistor designed for avionics applications operating between 1030 MHz and 1090 MHz. It features an internally matched design within a flanged ceramic SOT502A package, facilitating straightforward integration into transmitter circuits. The device delivers typical pulsed RF performance with 200 W output power, 20 dB gain, and 65% drain efficiency at a 28 V supply voltage. Key electrical characteristics include a drain-source breakdown voltage of 65 V and a junction temperature limit of 225 °C.

Feature Summary

• Internally matched for simplified circuit implementation
• Enhanced ruggedness capable of withstanding high VSWR mismatches
• Integrated electrostatic discharge (ESD) protection
• High thermal stability and broadband operational capability

Applications

• Avionics transmitter applications in the 1030 MHz to 1090 MHz frequency range

Procurement Notes

Verify the specific package variant required for the target application, as the BLA6G1011 series includes distinct physical configurations such as the straight lead SOT502A, earless flanged SOT502C, and eared flanged SOT502D. Confirm that the ordering suffix aligns with the mechanical mounting constraints and lead style specifications defined in the official Ampleon documentation before finalizing procurement.

Selection Notes

Select this component for avionics systems requiring robust RF power amplification in the 1030 MHz to 1090 MHz band. Ensure the design accommodates the specified 28 V supply voltage and manages heat dissipation effectively given the transient thermal impedance values. Verify that the chosen package version matches the PCB layout and mounting hole requirements of the host system.

Part Context

This part belongs to the BLA6G1011(L)(S)-200R(G) family from Ampleon, which encompasses multiple package variants including the BLA6G1011L-200RG and BLA6G1011LS-200RG. These devices share identical electrical specifications but differ in their physical housing styles, specifically regarding the presence or absence of ears on the flanged ceramic packages.

Replacement Considerations

Direct substitutes within the same electrical specification family include the BLA6G1011L-200RG and BLA6G1011LS-200RG. Selection among these depends strictly on the required mechanical package type: SOT502A for straight leads, SOT502D for eared flanges, or SOT502C for earless flanges.

FAQ

What is the maximum load mismatch the device can withstand?

The device is enhanced for ruggedness and can withstand a load mismatch corresponding to a VSWR of 10:1 through all phases under specified pulsed RF conditions.

How does the package type affect the pin configuration?

All variants (SOT502A, SOT502C, SOT502D) maintain the same pinout: Pin 1 is Drain, Pin 2 is Gate, and Pin 3 is Source, with the flange connected to the drain.

Is this component suitable for automotive applications?

No, unless explicitly stated otherwise in the data sheet, this product is not automotive qualified and is not tested according to automotive standards.
