MW6IC2420NBR1 Übersicht
A power amplifier (PA) is the final active stage of a transmitter signal chain that converts a low-level RF input into a high-power signal delivered to the antenna. The MW6IC2420NBR1 belongs to the LDMOS (Laterally Diffused Metal-Oxide Semiconductor) family of RF power transistors, integrated as a multi-stage MMIC inside a single plastic over-molded package. Its on-chip input and output matching networks eliminate external microstrip matching components, reducing PCB complexity and shrinking board area in 2.4 GHz transmitters.
Key features include 19.5 dB typical gain at 2.17 GHz, 20 W CW output capability at 28 V, integrated bias networks, ESD protection on all ports, and broadband matched operation across 2110–2450 MHz. The 50 Ω nominal input/output impedance simplifies PCB layout, and the TO-272 WB-16 ceramic-plastic package offers a thermal resistance suitable for continuous-wave duty with proper heatsinking.
Architecturally, the device is a two-stage cascade of LDMOS FET cells biased in Class AB for linear amplification, with internal inter-stage matching and a harmonic termination network optimized for CW operation. Compared to a discrete FET-plus-matching design, the integrated approach reduces part count and improves unit-to-unit gain consistency.
Typical applications include 2.4–2.5 GHz ISM transmitters, microwave oven driver stages, Wi-Fi 802.11b/g power amplifiers, RF heating systems, and digital video broadcast uplink equipment. When designing with the MW6IC2420NBR1, ensure the heatsink keeps the flange temperature below the datasheet maximum and provide a 28 V regulated supply with adequate decoupling to suppress low-frequency oscillation.

Typische Anwendungen
MW6IC2420NBR1 ist geeignet für 6 Anwendungs: 2.45 GHz ISM-Band Transmitters, Microwave Oven Driver Amplifier, Wi-Fi 802.11b/g Power Amplifier Front-End, RF Heating and Drying Systems, Digital Video Broadcast (DVB) Uplink Equipment, Industrial Process Heating RF Generators.
2.45 GHz ISM-Band Transmitters
The MW6IC2420NBR1 is purpose-built for the 2.4–2.5 GHz industrial-scientific-medical band, delivering 20 W CW output with on-chip matching that eliminates external microstrip networks. The 19.5 dB gain reduces the required driver-stage gain, and the 50 ohm input/output impedance simplifies PCB layout. In a typical ISM transmitter, it sits between a small-signal driver and the antenna, fed from a regulated 28 V rail through an LC decoupling network to suppress supply-borne noise that could otherwise modulate the output.
Empfohlen
Microwave Oven Driver Amplifier
Microwave-oven magnetron drivers and RF heating systems require continuous-wave RF power in the 2.45 GHz ISM band where the MW6IC2420NBR1 is optimized. Its 20 W CW capability at 28 V directly drives a magnetron cathode stage in solid-state replacement designs, replacing older tube-based drivers. The LDMOS architecture provides long operational life and the integrated matching reduces the tune-up variability of magnetrons across production runs.
Empfohlen
Wi-Fi 802.11b/g Power Amplifier Front-End
The MW6IC2420NBR1's 2.4 GHz coverage and 20 W capability make it a high-power final-stage option for industrial Wi-Fi amplifiers, outdoor mesh backhaul radios, and long-range bridge links. Its 19.5 dB gain reduces the number of driver stages required in the transmit chain. For 802.11b/g (DSSS/CCK modulation) the linearity is adequate, and the on-chip matching keeps board area small. Design note: the supply must be heavily decoupled to prevent OFDM/EVM degradation from 28 V rail ripple.
Empfohlen
RF Heating and Drying Systems
Industrial RF heating at 2.45 MHz-equivalent ISM band uses the MW6IC2420NBR1 as a CW power source driving applicators for drying textiles, paper, food and ceramics. The 20 W CW rating and 28 V LDMOS architecture provide reliable continuous duty when the flange is properly heatsinked. The 50 ohm interface simplifies connection to standard coaxial applicator feeds, and the integrated matching reduces the per-unit RF tune-up time in volume manufacturing.
Empfohlen
Digital Video Broadcast (DVB) Uplink Equipment
The MW6IC2420NBR1 covers the 2110–2170 MHz band where digital video broadcast uplink and terrestrial microwave links operate. Its 19.5 dB gain at 2.17 GHz and 20 W CW capability provide the final-stage power required for high-EIRP uplink transmitters. The LDMOS technology delivers the linearity needed for DVB modulation formats. The integrated matching reduces BOM and PCB area, which is critical in outdoor weatherproof transmitter housings where space and reliability matter.
Empfohlen
Industrial Process Heating RF Generators
Plasma generators, RF-curing systems and induction-style 2.45 GHz process heaters benefit from the MW6IC2420NBR1's 20 W CW capability and integrated matching. The LDMOS device simplifies RF generator design compared to discrete-FET-plus-microstrip implementations, reducing assembly time and tuning cost. Proper thermal management is essential: at 20 W CW output, several watts of internal dissipation must be removed through the package flange via a heatsink with thermal-interface material.

Wichtigste Unterscheidungsmerkmale
- On-chip input/output matching eliminates external microstrip networks (vs. Discrete 2.4 GHz LDMOS FET (e.g., MRF245))
- Two-stage integrated cascade with internal inter-stage matching (vs. Single-stage discrete LDMOS designs)
- Wide 2110–2450 MHz coverage in one part (vs. Narrow-band discrete designs)
Designhinweise
At 20 W CW RF output and 28 V supply, the MW6IC2420NBR1 dissipates several watts internally and requires a substantial heatsink attached to the package flange. Use a high-quality thermal-interface material (e.g., thermal pad rated > 1 W/m-K or thermal grease with a thin bond line) and mount the flange with the manufacturer-specified torque to minimize thermal resistance. Estimated: with 20 W output and a typical PAE figure around 50%, internal dissipation is approximately 18–22 W at full drive; the flange temperature must be monitored in production to verify the heatsink design meets the datasheet's junction temperature limit.
Use a multi-layer PCB with a continuous ground plane beneath the TO-272 footprint and 50 ohm microstrip or coplanar-waveguide traces for RFIN and RFOUT. Place the 28 V drain decoupling capacitors (typically a parallel combination of 100 nF ceramic and 10 µF tantalum or electrolytic) within a few millimeters of the VDD pins to suppress supply-borne low-frequency oscillation. Keep gate-bias traces short and shielded from the RF path to prevent feedback-induced instability.
The 28 V supply must be regulated with less than 100 mVpk-pk ripple across the full operating bandwidth; ripple on the drain modulates the RF output and degrades ACPR/EVM. Add a ferrite bead plus LC low-pass filter at the supply feed to the board. Include a soft-start circuit (or controlled ramp on the gate bias supply VGG) to limit inrush current when the PA is enabled, which prevents transient overstress of the LDMOS drain junctions during power-up sequencing.
Common pitfalls include exceeding the 32 V absolute maximum on the drain supply, omitting gate-bias sequencing (which can cause the device to draw excessive current on power-up), and operating the RF input above the datasheet's maximum drive level. Always verify the heatsink is properly attached before applying RF drive, and confirm the load VSWR is within 2:1 across the operating band - higher VSWR can drive the LDMOS into secondary breakdown.
