NXP Semiconductors BGX7101HN/1,115

Overview

The BGX7101HN/1,115 from NXP Semiconductors is a high-linearity RF transmitter IQ modulator supporting 400 MHz to 4000 MHz up-conversion with 650 MHz modulation bandwidth, 12 dBm P1dB output power, 27 dBm typical IP3o, and unadjusted sideband suppression of 50 dBc. It operates from a single 5 V supply and enables fast hardware-controlled power-down for base station transmitters.

For engineers reviewing the BGX7101HN/1,115 datasheet, BGX7101HN/1,115 pinout, BGX7101HN/1,115 application, or BGX7101HN/1,115 equivalent, key selection criteria include RF frequency coverage, LO input return loss (≥12 dB), differential IQ input impedance (100 Ω), RF output matching (50 Ω), and shutdown timing (<1 μs).

Technical Context

The BGX7101HN/1,115 integrates dual upconverter mixers with broadband LO splitting (0°/90°) and active biasing, enabling stable performance across 0.25 V–3.3 V IQ common-mode voltage. Its architecture supports supradyne mode operation and maintains consistent RF output return loss (≥10 dB) and LO input return loss (≥12 dB) over full frequency range.

It features independent RF and LO analog power domains (VCC_RF(5V0) and VCC_LO(5V0)), multiple dedicated ground pins per domain (LOGND, RFGND), and internally connected terminals tied to RF ground-enabling high isolation and low bond-wire inductance at RF ports.

Key Specifications

Pinout & Package

FAQ

What is the operating RF frequency range of the BGX7101HN/1,115?

The BGX7101HN/1,115 operates from 400 MHz to 4000 MHz, covering major cellular bands (700 MHz, 1.8 GHz, 2.1 GHz, 2.6 GHz, 3.5 GHz), microwave links, and broadband wireless standards. This range is validated across temperature (−40 °C to +85 °C) and supply (4.75–5.25 V), with consistent S11_LO ≥12 dB and S22_RF ≥10 dB.

Does the BGX7101HN/1,115 require external biasing components?

No, the BGX7101HN/1,115 incorporates integrated active biasing, eliminating the need for external resistors or current sources. This ensures stable gain and linearity over temperature and supply variations, simplifying PCB layout and improving repeatability in high-volume manufacturing.

How does the POFF_P pin function on the BGX7101HN/1,115?

The POFF_P pin (Pin 1) is an active-HIGH hardware control input: applying >1.5 V places the BGX7101HN/1,115 into low-current shutdown mode (<6 mA), while <0.5 V enables active operation. Transition time between states is under 1 μs, and LO impedance remains stable during switching to avoid synthesizer unlock in base station TDD systems.

What are the input impedance and common-mode voltage range for the IQ baseband inputs of the BGX7101HN/1,115?

The BGX7101HN/1,115 provides 100 Ω differential input impedance on both MODI and MODQ paths, with guaranteed operation across a 0.25 V to 3.3 V common-mode voltage range. This allows direct interface to a broad range of high-speed DACs without level-shifting or AC-coupling adjustments.

Is the BGX7101HN/1,115 pin-compatible with other NXP IQ modulators like the BGX7100?

No, the BGX7101HN/1,115 is not pin-compatible with the BGX7100. It uses a distinct 24-pin HVQFN24 (SOT616-3) footprint with dedicated VCC_RF(5V0) and VCC_LO(5V0) supplies, separate LOGND/RFGND domains, and different pin assignments-including POFF_P at Pin 1 and RFOUT at Pin 16-which differ from earlier variants.
