MW7IC2220NR1 개요
An RF power amplifier (RF PA) is the final amplification stage in a wireless transmitter chain, boosting low-level radio signals from the transceiver up to the watt-level power required to drive the antenna, and it directly determines cellular base-station range, linearity, and link budget. Within the transmitter hierarchy, the RF PA sits after the up-conversion mixer and before the duplexer/filter, and it belongs to the LDMOS (Laterally Diffused Metal-Oxide Semiconductor) family of high-frequency power transistors that dominate cellular infrastructure below ~3 GHz because of their high gain, high efficiency, and excellent ruggedness. The MW7IC2220NR1 specifically targets the cellular downlink band 2110-2170 MHz, supports W-CDMA, TD-SCDMA and similar modulation formats, and integrates a two-stage amplifier structure in a single die.
Key specifications include 31 dB small-signal gain, 28 V typical drain supply, 300 mA quiescent current (IDQ2), and an operational frequency range from 2000 MHz to 2200 MHz per the manufacturer's wideband test fixture characterization. The on-chip matching allows the part to be used directly in 50 ohm reference designs without external impedance transformation networks, simplifying both the schematic and PCB layout.
Architecturally, the device is a two-stage LDMOS amplifier with internal inter-stage matching and bias networks optimized for W-CDMA linearity. The NXP datasheet specifies ACPR (Adjacent Channel Power Ratio) performance measured under 3.84 MHz channel bandwidth and +/-5 MHz offset in the Freescale 2110-2170 MHz test fixture, with the input signal at 7.5 dB PAR, providing a realistic worst-case linearity reference for system designers.
Typical applications include W-CDMA/TD-SCDMA base-station driver or output stages, 2.1 GHz band pico-cell and femto-cell power amplifiers, repeater and small-cell transmit chains, and general-purpose 2000-2200 MHz RF amplification where high gain and rugged LDMOS performance are required.
When designing with this part, allocate enough PCB copper area under the exposed flange for thermal dissipation and follow the NXP reference layout and bias sequence recommendations. Designers should also respect the absolute maximum drain voltage of 32 V and provide proper sequencing on VGG to prevent device damage during power-up.

일반적인 애플리케이션
MW7IC2220NR1 적합 용도: 6 애플리케이션s: W-CDMA Small-Cell Base Station, TD-SCDMA Repeater and Booster, Pico-Cell and Femto-Cell Transmit Chain, 2 GHz General RF Amplification, Wireless Backhaul Driver Stage, Multi-Stage Cellular PA Reference Design.
W-CDMA Small-Cell Base Station
The MW7IC2220NR1's 31 dB integrated gain and on-chip 50 ohm matching make it ideal for the final PA stage in 2110-2170 MHz W-CDMA small-cell base stations, where PCB area is constrained and design reuse is critical. The 2 W average output capability covers the typical micro-cell downlink output requirement when paired with external digital predistortion (DPD). Per the NXP MW7IC2220N datasheet, ACPR measured with single-carrier W-CDMA at 7.5 dB PAR remains compliant across the 2110-2170 MHz band, simplifying DPD loop calibration and reducing the time-to-market for small-cell OEMs.

TD-SCDMA Repeater and Booster
The MW7IC2220NR1 is well-matched to TD-SCDMA repeater/booster transmit chains operating in the 2010-2025 MHz uplink and 1900-1920 MHz adjacent bands, thanks to its 2000-2200 MHz broadband match. The TO-270WB-16 flange package allows direct bolting to an aluminum chassis for heatsinking, which is essential when running the device near its 25 W CW P1dB compression point for linearity-critical booster applications. According to the manufacturer datasheet, the device is 100% PAR tested under single-carrier W-CDMA conditions, giving repeater designers confidence in the linearity margin across typical input signals.
추천
Pico-Cell and Femto-Cell Transmit Chain
Inside a femto-cell or pico-cell, the MW7IC2220NR1 can serve as the final PA after the transceiver and DPD block, where its 2 W average W-CDMA output capability matches the typical 100-2000 mW picocell downlink requirement with margin. The two-stage integrated architecture eliminates an external driver stage, reducing the BOM count and shrinking the PCB footprint needed for the RF chain. Engineers can also reuse this part across UMTS, TD-SCDMA, and single-carrier W-CDMA picocells, simplifying platform firmware and hardware variants.

2 GHz General RF Amplification
Beyond cellular standards, the MW7IC2220NR1's broadband on-chip matching and 31 dB gain support laboratory, instrumentation, and RF front-end designs that need high gain at 2-2.2 GHz. Engineers can use it as a general-purpose 2 GHz block amplifier in test sets, RF-over-fiber transmit modules, or driver for higher-power boosters where its 100% PAR tested linearity provides predictable gain versus frequency. Its 25 W typical P1dB makes it easy to operate as a CW amplifier in engineering lab work without the need for a tunable matching network.
추천
Wireless Backhaul Driver Stage
For 2 GHz point-to-point wireless backhaul radios that need a rugged, high-linearity PA driver, the MW7IC2220NR1 provides 2 W average output with 31 dB gain in a flange-mounted TO-270WB-16 package that can be bolted directly to a chassis for thermal performance. The 100% PAR testing for single-carrier W-CDMA per the datasheet demonstrates excellent tolerance to high PAPR signals like those used in OFDM-based backhaul modulation. Designers benefit from the on-chip 50 ohm matching, which simplifies the backhaul system's RF PCB layout and reduces tuning time on the production line.

Multi-Stage Cellular PA Reference Design
The MW7IC2220NR1 is featured in the NXP Cellular Infrastructure Reference Design library as the integrated two-stage driver stage, providing 31 dB of gain ahead of a higher-power final LDMOS FET such as the AFT27S006N or BLF7G22LS-160. This Doherty or class-AB topology reference design enables macro-cell base-station PA designers to leverage the part's on-chip matching and bias sequencing to accelerate their own design cycles. The reference design typically pairs the MW7IC2220NR1 with a digital predistortion (DPD) engine, simplifying the path to production for 4G LTE and 5G NR base-station radio units.

설계 노트
Estimated: at 2 W W-CDMA average output with 28 V drain, the LDMOS dissipation reaches several watts continuous, so the TO-270WB-16 back metal MUST be bolted to a heatsink or chassis using thermal compound and a thin washer. Without heatsinking, junction temperature will exceed 150 C and the device will thermally fold back or fail. Provide at least 4 square inches of copper spreader area and a forced-air path during engineering characterization to verify Tj margin.
Place the RF input and RF output traces on a coplanar waveguide with ground (CPWG) stackup using the same dielectric as the rest of the RF chain. Keep DC bias traces (VGG1, VGG2, VDD1, VDD2) routed away from the RF traces to avoid coupling. Follow the NXP MW7IC2220N evaluation board layout 1:1 whenever possible - the on-chip matching is optimized for the reference fixture's PCB stackup, and deviations typically cost 0.5 dB of gain and several points of ACPR.
Do not apply VDD before VGG when powering up - always sequence VGG negative voltage first to avoid forward-biasing the gate-source junction. Never exceed 32 V on VDD per the datasheet absolute maximum rating, and never allow the RF input to be hot while VDD is unpowered because reverse leakage can damage the die. Use a gate-source pull-down resistor on each VGG line so the part defaults to a safe bias state during fault conditions.
