Product details
Overview
The MAX2829ETN from Maxim Integrated is a dual-band RF transceiver IC designed for IEEE 802.11a/b/g WLAN systems, covering 2.4–2.5GHz and 4.9–5.875GHz bands. It integrates full Rx/Tx signal paths, on-chip monolithic filters, VCO, frequency synthesizer, and 3-wire serial interface - eliminating external SAW filters and enabling compact front-end designs for MIMO and smart antenna radios.
For engineers reviewing the MAX2829ETN datasheet, MAX2829ETN pinout, MAX2829ETN application, or MAX2829ETN equivalent, this page delivers verified RF performance specs (e.g., −75dBm Rx sensitivity at 54Mbps 802.11g), dual-band frequency coverage, integrated calibration features, and MIMO-compatible LO phase coherence - all critical for 802.11a/b/g radio design and regulatory-compliant RF layout.
Technical Context
The MAX2829ETN implements a direct-conversion architecture with I/Q baseband interface, supporting both OFDM (6–54Mbps) and CCK/DSSS (1–11Mbps) modulation schemes. Its integrated PLL uses a 40MHz reference oscillator and achieves −100dBc/Hz (802.11g) / −95dBc/Hz (802.11a) closed-loop phase noise at 10kHz offset.
It features programmable baseband lowpass filters (nominal, turbo mode 1/2), 93dB (802.11g)/97dB (802.11a) receiver gain-control range, and Tx/Rx I/Q error detection. Coherent LO phase among multiple transceivers enables synchronized MIMO operation without external alignment circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2828ETN | Single-band only (4.9–5.875GHz); lacks 2.4GHz support and associated baseband calibration registers. | Restricted to 5GHz-only 802.11a or public safety radios; cannot replace MAX2829ETN in dual-band designs. | Select MAX2828ETN only when 2.4GHz operation is unnecessary and board layout must be optimized for 5GHz-only RF path. |
| AD9361BBCZ | Wideband (70MHz–6.0GHz), software-defined architecture; requires external filters, higher power (1.2W typical), larger 144-pin CSPBGA package. | Suitable for multi-standard (LTE/Wi-Fi/Zigbee) SDR platforms but over-engineered for fixed 802.11a/b/g use cases. | Choose AD9361BBCZ only if future protocol flexibility, tunable bandwidth, or sub-GHz support is required - not for cost- or size-optimized 802.11 radios. |
Compared with MAX2828ETN and AD9361BBCZ, the MAX2829ETN delivers optimal integration for dedicated dual-band 802.11a/b/g radios - combining band-specific RF performance, on-chip filtering, and MIMO-ready timing in a compact 56-pin QFN, avoiding both the band limitation of MAX2828ETN and the complexity/power overhead of AD9361BBCZ.

FAQ
What is the operating frequency range supported by the MAX2829ETN?
The MAX2829ETN supports two distinct RF bands: 2.412–2.500GHz for 802.11b/g operation and 4.900–5.875GHz for 802.11a and public safety applications. This dual-band capability allows a single MAX2829ETN to replace separate 2.4GHz and 5GHz transceivers in unified WLAN radios, reducing system complexity and PCB area.
Does the MAX2829ETN require external SAW filters?
No, the MAX2829ETN does not require external SAW filters. It integrates monolithic RF filters in both the receive and transmit paths, explicitly designed to meet IEEE 802.11a/g spectral mask requirements without additional filtering components. This integration reduces bill-of-materials cost, simplifies layout, and improves reliability compared to discrete filter solutions.
How does the MAX2829ETN support MIMO systems?
The MAX2829ETN supports MIMO through coherent LO phase alignment across multiple units - ensuring deterministic phase relationships between transceivers without external LO distribution. Its 3-wire serial interface allows synchronized register writes, and its Rx/Tx calibration loop maintains I/Q accuracy across temperature, enabling robust spatial processing in 2×2 or 3×3 antenna configurations.
What is the receiver sensitivity of the MAX2829ETN at 54Mbps 802.11g?
The MAX2829ETN achieves −75dBm receiver sensitivity at 54Mbps under 802.11g conditions, which is up to 10dB better than the minimum IEEE 802.11g standard requirement. This enhanced sensitivity extends range and improves link robustness in interference-prone environments such as dense urban deployments or industrial facilities.
What package type and thermal characteristics does the MAX2829ETN use?
The MAX2829ETN uses a 56-pin thin QFN package with exposed thermal paddle (T5688-2, 8mm × 8mm). The exposed paddle provides low thermal resistance to the PCB, enabling efficient heat dissipation during continuous Tx operation. Its specified continuous power dissipation is 2500mW at +70°C ambient, derating linearly above that temperature.
