NXP Semiconductors BGX7101HN/1,118

Overview

BGX7101HN/1,118 from NXP Semiconductors is a high-linearity transmitter IQ modulator for RF up-conversion in 400 MHz–4000 MHz systems. It delivers 12 dBm output at 1 dB gain compression, 27 dBm typical output IP3, 50 dBc unadjusted sideband suppression, and operates from a single 5 V supply with 100 Ω differential IQ input impedance. It enables broadband wireless infrastructure transmitters requiring stable modulation performance across wide common-mode voltage (0.25 V–3.3 V) and frequency ranges.

For engineers reviewing the BGX7101HN/1,118 datasheet, BGX7101HN/1,118 pinout, BGX7101HN/1,118 application, or BGX7101HN/1,118 equivalent, key selection criteria include RF bandwidth support (up to 650 MHz modulation BW), fast hardware-controlled power-down (<1 μs transition), LO impedance stability during shutdown, and compatibility with standard DAC interfaces via 100 Ω differential input termination.

Technical Context

The BGX7101HN/1,118 integrates dual upconverter mixers with independent I and Q paths, each accepting 100 Ω differential baseband inputs. Its LO path includes internal 0°/90° phase splitting and buffering, enabling precise quadrature modulation without external phase shifters. The device uses integrated active biasing and supports supradyne operation.

Performance remains stable across IQ common-mode voltages from 0.25 V to 3.3 V, eliminating need for level-shifting circuitry when interfacing with diverse DAC families. Shutdown is controlled by an active-HIGH POFF_P pin, and LO input return loss exceeds 12 dB across the full 400–4000 MHz band, ensuring minimal synthesizer perturbation during power cycling.

Key Specifications

Pinout & Package

The BGX7101HN/1,118 is housed in a 4 mm × 4 mm × 0.85 mm HVQFN24 package (SOT616-3) with exposed die pad for thermal and RF grounding. Pin layout separates LO, RF, and IQ domains with multiple dedicated ground pins (LOGND, RFGND) and independent 5 V supplies for LO (VCC_LO) and RF (VCC_RF) sections to minimize crosstalk.

FAQ

What is the RF frequency range supported by the BGX7101HN/1,118?

The BGX7101HN/1,118 supports an RF frequency range from 400 MHz to 4000 MHz, covering major cellular bands (LTE, 5G NR FR1), microwave links (6–42 GHz via IF up-conversion), and broadband wireless standards. This range is validated across temperature and supply variations per the official NXP datasheet Rev. 5.

Does the BGX7101HN/1,118 require external LO phase-shifting components?

No, the BGX7101HN/1,118 integrates an internal LO buffer and 0°/90° splitter, eliminating the need for external quadrature hybrid couplers or phase-shift networks. This simplifies PCB layout and improves amplitude/phase balance between I and Q paths compared to discrete LO distribution approaches.

What is the differential input impedance of the BGX7101HN/1,118 IQ ports?

The BGX7101HN/1,118 features a nominal 100 Ω differential input impedance on both MODI and MODQ ports, enabling direct interface with standard current-output DACs and baseband filters without external termination resistors - confirmed in Table 6 and Section 8.1 of the datasheet.

How does the POFF_P pin function on the BGX7101HN/1,118?

The POFF_P pin (Pin 1) is an active-HIGH logic input that places the BGX7101HN/1,118 into low-current shutdown mode when driven above 1.5 V. Transition time between active and inactive states is under 1 μs, and LO input impedance remains stable during switching - preventing synthesizer unlock in base station TDD applications.

Is the BGX7101HN/1,118 compatible with DACs operating at different common-mode voltages?

Yes, the BGX7101HN/1,118 maintains stable modulation performance across a 0.25 V to 3.3 V IQ common-mode voltage range, allowing direct connection to a broad family of DACs (e.g., AD916x, DAC38J84) without level-shifting circuitry - a key feature documented in Sections 1, 2, and 8.1 of the datasheet.
