BLM9D1822-30BX

Product Overview

BLM9D1822-30BX is a LDMOS RF power transistor / RF power amplifier device from Ampleon. In an RF design it is normally used as a final or driver PA device in a matched RF power stage, so the useful sourcing checks are not only the ordering code but also the operating band, gain behavior, output level, package footprint and bias conditions.

The base number places this device in the 1800 MHz to 2200 MHz family (derived from the BLM 18/22 band code); the suffix identifies the ordering or packing variant. Output power and linearity must be evaluated with the manufacturer's reference circuit because the same LDMOS device can behave differently when drain bias, load impedance or heat spreading changes.

Key Features

• Manufacturer: Ampleon
• Part Number: BLM9D1822-30BX
• Device Type: LDMOS RF power transistor / RF power amplifier device
• Signal-Chain Role: final or driver PA device in a matched RF power stage
• Frequency / Band: 1800 MHz to 2200 MHz family (derived from the BLM 18/22 band code)
• Gain / NF / Linearity: load-pull/reference-circuit gain and efficiency must be taken from the Ampleon datasheet, not estimated from package alone
• Output Power / Compression: 30 W class LDMOS power-amplifier family
• Supply / Bias: high-current LDMOS drain bias with thermal design requirement
• RF Interface: RF input/output through external impedance matching and heat spreading
• Package / Mounting: surface-mount RF IC, MMIC, transistor or connectorized module depending on base number
• Design Note: verify S-parameters, matching network, thermal pad/flange and control pins before substituting this RF amplifier

Applications

• cellular base-station power amplifiers
• broadcast/ISM RF power modules
• Doherty or linear PA designs
• legacy PA-board repair sourcing
