Product details
Overview
BGX7221HN/1,518 from NXP Semiconductors is a dual high-linearity RF down-converter mixer for receiver front-ends with shared LO, covering 1400–2700 MHz; delivers 8 dB conversion gain at 2 GHz, ICP1dB >13 dBm, IIP3 = 26 dBm, and 10 dB small-signal NF-used in mobile infrastructure diversity receivers.
For engineers reviewing the BGX7221HN/1,518 datasheet, BGX7221HN/1,518 pinout, BGX7221HN/1,518 application, or BGX7221HN/1,518 equivalent, key selection criteria include dual-mixer isolation (55 dB), independent hardware power-down control per channel, 5 V single-supply operation, and matched 50 Ω RF/LO input impedance.
Technical Context
The BGX7221HN/1,518 integrates two fully independent Gilbert-cell-based down mixers sharing a common LO path, enabling simultaneous main/diversity signal processing without inter-channel crosstalk. Each channel features active biasing and dedicated power-down pins, supporting dynamic channel gating in multi-path receivers.
It operates with 50 Ω single-ended RF and LO inputs across 1400–2700 MHz, delivering consistent 8 dB conversion gain in the 2 GHz band while maintaining 26 dBm IIP3 and 13 dBm ICP1dB under matched conditions-critical for LTE/TD-LTE base station receiver linearity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Freq. Range | 1400–2700 MHz: supports full-band LTE, WiMAX, and TD-SCDMA infrastructure receivers. |
| Conversion Gain | 8 dB at 2 GHz: enables direct interface to IF amplifiers without intermediate gain staging. |
| IIP3 | 26 dBm: ensures robust two-tone intermodulation rejection in dense RF environments. |
| ICP1dB | >13 dBm: allows handling of strong adjacent-channel signals before compression onset. |
| Noise Figure | 10 dB (small-signal): maintains SNR integrity in weak-signal reception scenarios. |
| Mixer Isolation | 55 dB typical: prevents signal leakage between main and diversity paths in MIMO systems. |
| Supply Voltage | 5 V single supply: simplifies power architecture versus dual-rail or negative-bias solutions. |
Pinout & Package
Package: HVQFN24 (4 × 4 mm, 0.5 mm pitch, exposed thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | 5 V supply for both mixers; requires local 100 nF + 1 µF decoupling. |
| GND | Ground reference | Common ground for RF, LO, IF, and bias networks; tied to exposed thermal pad. |
| RF1_IN / RF2_IN | Dual RF signal inputs | 50 Ω single-ended inputs for main/diversity antenna paths; DC-coupled. |
| LO_IN | Shared local oscillator input | 50 Ω single-ended LO drive; enables synchronous mixing without LO routing complexity. |
| IF1_OUT / IF2_OUT | Dual IF differential outputs | DC-coupled differential outputs (typically 200 Ω load) for baseband/IF processing. |
| PD1 / PD2 | Independent power-down controls | Active-low digital inputs; disable respective mixer core to reduce quiescent current to <10 µA. |
| BIAS | Internal bias reference | Not user-accessible; internal active biasing eliminates external resistor networks. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-mixer integration with shared LO | Reduces PCB area and LO distribution loss vs. discrete mixer pairs in diversity receivers. |
| Independent hardware power-down per channel | Enables real-time channel shutdown during idle periods-critical for TDD-based infrastructure power management. |
| Integrated active biasing | Eliminates external bias resistors and temperature drift compensation components. |
| 50 Ω matched RF/LO inputs | Minimizes external matching network requirements and insertion loss in 50 Ω system designs. |
| ESD protection on all pins | Withstands ≥2 kV HBM-supports robust handling during board assembly and field deployment. |
Applications
| Mobile Infrastructure Diversity Receiver | LTE Base Station IF Chain |
|---|---|
Use Scenario: Dual-antenna LTE eNodeB with main/diversity paths operating in 1800–2600 MHz bands. IC Role / Device Role / Timing Role: Dual down-converter translating RF to low-IF/baseband while preserving signal integrity and isolation. Use Value: 55 dB inter-mixer isolation prevents cross-talk; 26 dBm IIP3 handles co-site interference without distortion. | Use Scenario: High-dynamic-range IF stage in macrocell BTS requiring stable gain and noise performance. IC Role / Device Role / Timing Role: First-stage down-mixer converting 2.1 GHz UMTS/LTE signals to 100–300 MHz IF. Use Value: 8 dB conversion gain reduces need for additional IF amplification; 10 dB NF preserves overall receiver sensitivity. |
| TD-LTE TDD Base Station | Industrial Broadband Wireless Link |
Use Scenario: Time-division duplexed small cell with rapid transmit/receive switching and channel gating. IC Role / Device Role / Timing Role: Dual mixer with independent PD1/PD2 enabling per-path power cycling synchronized to TDD frame timing. Use Value: Power-down current <10 µA per channel extends operational efficiency during receive-only slots. | Use Scenario: Fixed wireless access unit operating in 2.3–2.7 GHz licensed bands for last-mile connectivity.

Use Value: Integrated ESD protection (≥2 kV HBM) and 5 V single supply simplify ruggedized design and reduce BOM count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual down-mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADL5365ACPZ-R7 | Single-channel, 700–1000 MHz LO range; no integrated power-down; requires external biasing. | Targeted at narrowband IF sampling, not dual-path infrastructure receivers. | Choose only if frequency range and single-channel operation align with legacy IF architecture. |
| MAX19995AETX+ | Dual-channel with 1700–2700 MHz coverage, but uses 3.3 V supply and lacks independent PD pins. | Suitable for compact SDR platforms where supply voltage and layout space constrain alternatives. | Select when 3.3 V compatibility and smaller package (TQFN20) outweigh need for per-channel power gating. |
Compared with ADL5365ACPZ-R7 and MAX19995AETX+, the BGX7221HN/1,518 uniquely supports independent hardware power-down per mixer on a 5 V rail within 1400–2700 MHz-enabling optimized power management in TDD-based diversity receivers without sacrificing linearity or isolation.

FAQ
What is the operating frequency range of the BGX7221HN/1,518?
The BGX7221HN/1,518 operates from 1400 MHz to 2700 MHz, covering key bands for LTE (1800/2100/2600 MHz), TD-LTE (2300/2500 MHz), and WiMAX (2500 MHz). This range is verified in NXP's official datasheet and confirmed by RF characterization across the full band.
Does the BGX7221HN/1,518 support independent power-down for each mixer channel?
Yes, the BGX7221HN/1,518 provides dedicated active-low PD1 and PD2 pins for independent hardware-controlled power-down of each mixer channel. When asserted, each channel draws less than 10 µA, enabling precise TDD slot gating-functionality explicitly documented in the NXP BGX7221HN/1,518 datasheet.
What is the noise figure specification for the BGX7221HN/1,518 under small-signal conditions?
The BGX7221HN/1,518 has a typical small-signal noise figure of 10 dB, measured at 2 GHz with 50 Ω source impedance. Under large-signal blocking conditions, the noise figure degrades to ~20 dB-both values are specified in the NXP product documentation and validated in production test data.
Is external biasing required for the BGX7221HN/1,518?
No, the BGX7221HN/1,518 incorporates integrated active biasing circuitry. This eliminates the need for external bias resistors or temperature-compensation networks, reducing BOM count and improving bias stability over temperature-confirmed in the NXP BGX7221HN/1,518 application schematic and functional description.
What package type is used for the BGX7221HN/1,518?
The BGX7221HN/1,518 is housed in a 24-pin HVQFN package measuring 4 mm × 4 mm with 0.5 mm pitch and an exposed thermal pad. This package is specified in the NXP ordering information and mechanical drawings, and supports reflow soldering per JEDEC J-STD-020 standards.
