Frequently Asked Questions
Q1: What does suffix -T1-A mean for NE5550979A-T1-A?
A: -T1 stands for tape & reel packing, 1000 pieces per reel; suffix -A indicates lead-free, RoHS green version released by CEL.
Q2: What is the recommended operating voltage for this LDMOS transistor?
A: Standard test and recommended supply voltage is 7.5V DC. Its absolute maximum drain-source voltage reaches 30V, do not exceed rated limit in circuit design.
Q3: Can NE5550979A-T1-A work at 900MHz?
A: Yes. This transistor supports 150MHz /460MHz /900MHz VHF-UHF bands. Optimal performance data is tested at 460MHz.
Q4: Are there alternative compatible RF transistors I can consider?
A: Similar UHF LDMOS alternatives include NXP and Ampleon medium power RF devices. Compare package size, voltage, gain and output power before replacement; pin compatibility requires PCB testing.
Q5: How to handle thermal design of the 79A package?
A: The exposed thermal pad must be fully soldered to PCB ground plane. Arrange multiple thermal vias under the pad to connect bottom copper layer and reduce junction temperature.
Q6: Can I use this part in Class-C amplifier circuit?
A: The datasheet specifications are defined for AB-class application. It can work under Class-C, but gain, PAE and linearity will change. Hardware verification is required for your project.
