NXP Semiconductors BGX7220HN/1,518

Overview

BGX7220HN/1,518 from NXP Semiconductors is a dual high-linearity RF down-mixer IC designed for receiver front-ends with shared local oscillator architecture, supporting main/diversity paths in 700–950 MHz cellular and infrastructure applications. It delivers 8 dB conversion gain at 900 MHz, 13 dBm ICP1dB, 26 dBm IP3i, and <10 dB small-signal noise figure under 5 V single-supply operation.

For engineers reviewing the BGX7220HN/1,518 datasheet, BGX7220HN/1,518 pinout, BGX7220HN/1,518 application, or BGX7220HN/1,518 equivalent, this page provides verified functional context, validated pin-level circuit roles, confirmed RF performance across temperature and supply voltage, and real-world diversity-receiver use cases requiring high isolation and independent power-down control.

Technical Context

The BGX7220HN/1,518 integrates two independent passive MOS mixers with transformer-coupled single-ended RF and LO inputs, each driving an open-collector IF amplifier stage referenced to 5 V for maximum swing. Its dual-path architecture enables simultaneous or selective activation via POFF_1/POFF_2 logic inputs, with sub-10 µs transition time between active and shutdown states.

Each mixer features matched 50 Ω RF/LO input impedance, integrated active biasing, and ESD protection on all pins. The HVQFN36 package includes an exposed paddle serving as RF/DC ground, and multiple dedicated VCC/GND domains isolate RF, LO, and IF sections to maintain >55 dB inter-mixer isolation.

FAQ

What is the RF input frequency range supported by the BGX7220HN/1,518?

The BGX7220HN/1,518 supports an RF input frequency range of 700 MHz to 950 MHz, optimized for cellular bands including LTE Bands 12, 13, 17–20, and 26–28. Operation outside this range is possible but not guaranteed per specification. This range aligns precisely with North American and European low-band LTE infrastructure deployments where the BGX7220HN/1,518 is commonly deployed.

Does the BGX7220HN/1,518 require external biasing components?

No, the BGX7220HN/1,518 incorporates integrated active biasing circuitry, eliminating the need for external bias resistors or current-setting networks. This simplifies layout, improves temperature stability of conversion gain and noise figure, and reduces bill-of-materials cost. All bias currents are internally regulated from the 5 V supply rails specified in the BGX7220HN/1,518 datasheet.

How is isolation between Mixer A and Mixer B achieved in the BGX7220HN/1,518?

Isolation between Mixer A and Mixer B in the BGX7220HN/1,518 is achieved through physical separation of RF/IF ground domains, dedicated VCC supply lines for each functional block (RF, LO, IF), and internal shielding within the HVQFN36 package. Measured inter-mixer isolation is typically 55 dB, enabling clean diversity signal processing without cross-talk-critical for the BGX7220HN/1,518's role in base station receiver architectures.

What are the power-down modes supported by the BGX7220HN/1,518?

The BGX7220HN/1,518 supports four power-down modes controlled by POFF_1 and POFF_2 logic inputs: Active (0,0), Idle (1,0), Main (0,1), and Diversity (1,1). In Idle mode, both mixers are off but the common LO buffer remains active for port matching. Transition time between states is under 10 µs, enabling rapid reconfiguration-key for TDD-based systems using the BGX7220HN/1,518.

Can the BGX7220HN/1,518 operate with a 3.3 V supply?

No, the BGX7220HN/1,518 is specified for 4.75 V to 5.25 V operation only. Attempting to power it from 3.3 V will result in improper biasing, degraded conversion gain, increased noise figure, and potential failure to meet ICP1dB or IP3i specifications. The BGX7220HN/1,518's internal regulator (VCC(REG) pin 21) and all functional blocks are designed exclusively for 5 V operation.
