Frequently Asked Questions
Q1: What frequency band fits BLM10D3438-35AB?
A: 3400MHz–3800MHz, suitable for 5G NR n77, n78 and C-band base stations.
Q2: Difference between BLM10D3438-35AB and BLM10D3438-35ABZ?
A: Same die, electrical specs and package. The suffix Z means tape & reel packing. They are pin-to-pin interchangeable.
Q3: Can it run on 26V supply?
A: Nominal voltage is 28V. It supports 26V operation, with slightly lower output power, gain and efficiency. Refer to datasheet curves.
Q4: Advantages of integrated 3-stage Doherty design?
A: Built-in splitter, combiner & matching circuits. It delivers ≥33dB gain, saves PCB space and reduces peripheral components.
Q5: Any alternative Ampleon Doherty MMIC for 3.4–3.8GHz?
A: BLM10D3740-35AB is an alternative with wider frequency range. Matching adjustment may be needed before replacement.
Q6: Can cross-brand RF LDMOS directly replace this device?
A: Not recommended. Different internal circuits and bias settings. Full RF testing is required after replacement.
Q7: What voltage and output power does this module provide?
A: Nominal 28V supply voltage, peak output power up to 35W.
Q8: Are external power splitters or combiners needed?
A: No. Splitter and combiner are fully integrated inside the package to simplify design.
