NXP Semiconductors OM7602/BGA2022/2450

Overview

BGA2022 from NXP Semiconductors is a silicon double-poly MMIC mixer in SOT363 package, designed for RF-to-IF downconversion in wireless receivers. It delivers 6 dB typical conversion gain at 1800 MHz, 12 dB DSB noise figure, and +7 dBm output IP3 at 1800 MHz, operating from 2.8 V supply with only 6 mA current - enabling high-linearity, low-power reception in CDMA and WLAN systems.

For engineers reviewing the BGA2022 datasheet, BGA2022 pinout, BGA2022 application, or BGA2022 equivalent, this page provides verified RF mixer specifications, validated SOT363 terminal mapping, confirmed frequency-band performance (900/1800/1950/2450 MHz), and real-world design constraints including AC-coupled LO/RF inputs and ground-tab thermal resistance of 375 K/W.

Technical Context

The BGA2022 integrates a passive double-balanced topology with on-chip biasing, optimized for fixed-frequency IF outputs (e.g., 80 MHz or 280 MHz) across cellular, PCS, and 2.4 GHz WLAN bands. Its RF input impedance varies with frequency (e.g., ~400 Ω + j300 Ω at 1800 MHz), requiring external matching per band.

Conversion gain is LO-power dependent (peaking near 0 dBm), and supply current remains stable from 2.8 V to 4 V. The device requires no external DC on pins 1, 2, or 6 - all RF/LO paths are AC-coupled to 50 Ω sources, and thermal management relies on solder-point conduction via the exposed ground tab.

FAQ

What is the maximum RF input power the BGA2022 can handle?

The BGA2022 has a maximum RF input power rating of +10 dBm under AC-coupled, 50 Ω source conditions. Exceeding this may cause compression or permanent damage. At +10 dBm RF input, the device maintains linearity up to its +7 dBm OIP3 point, but conversion gain compresses above −10 dBm input. Always use external attenuation or limiting if RF signals exceed −5 dBm in production designs.

Does the BGA2022 require external bias components besides the RF feedback resistor?

No - the BGA2022 integrates all bias circuitry on-die. Only an external RF feedback resistor (e.g., 22 Ω between Pins 5 and 6) and standard supply decoupling (e.g., 100 nF ceramic at Pin 3) are required. Pins 1 and 2 form a differential AC-coupled LO port with no DC path; Pin 6 is AC-coupled RF input - no external bias resistors or current-setting networks are needed for basic operation of the BGA2022.

Can the BGA2022 be used with a 500 MHz IF output?

No - the BGA2022 is characterized and optimized for IF outputs of 80 MHz and 280 MHz only. At 500 MHz, IF output impedance becomes highly reactive (Fig.4 shows rising −jX dominance), causing severe mismatch and gain roll-off. Application note AN00059 confirms valid IF frequencies are limited to 80 MHz and 280 MHz; using 500 MHz would degrade conversion gain by >6 dB and increase noise figure unpredictably in the BGA2022.

What is the recommended PCB layout practice for the BGA2022 ground tab?

The exposed ground tab on the BGA2022 (SOT363 package) must be soldered directly to a solid, low-impedance PCB ground plane covering ≥1 cm². Thermal vias (≥4× 0.3 mm diameter) should connect the tab to inner-layer ground planes to achieve effective R_{th j–s} ≈ 375 K/W. Avoid routing traces under the tab or splitting the ground plane beneath it - doing so raises junction temperature and degrades conversion gain stability in the BGA2022.

Is the BGA2022 pin-compatible with the BGA2020 or BGA2021?

No - the BGA2022 is not pin-compatible with BGA2020 or BGA2021. Although all three are SOT363-packaged MMIC mixers, their pin functions differ: BGA2020 uses Pin 5 as VS and Pin 3 as IF-out, while BGA2022 assigns Pin 3 to VS and Pin 4 to IF-out. Swapping them without board revision will result in incorrect biasing and non-functional operation of the BGA2022.
