Product details
Overview
MAX7060ATG+ from Maxim Integrated is a fully integrated, frequency- and power-programmable ASK/FSK RF transmitter IC operating from 280MHz to 450MHz. It features a fractional-N PLL synthesizer, programmable PA output power from +14dBm down to –14dBm (at 5V), 24-pin TQFN package, and supports Manchester-encoded data rates up to 50kbps (ASK) and 70kbps (FSK). It is widely used in automotive-grade remote controls and garage-door openers.
For engineers reviewing the MAX7060ATG+ datasheet, MAX7060ATG+ pinout, MAX7060ATG+ application, or MAX7060ATG+ equivalent, key selection criteria include its 28dB programmable transmit power range in 1dB steps, ultra-fast <250µs startup time, FCC Part 15 and ETSI EN 300 220 compliance (up to +6dBm EIRP), and dual-mode SPI/manual configuration capability.
Technical Context
The MAX7060ATG+ implements a crystal-referenced fractional-N PLL with VCO gain of 340MHz/V and loop bandwidth of 300kHz, enabling precise frequency synthesis across its 280–450MHz band using a single 15–16MHz crystal. Its programmable matching capacitor (0–7.75pF) dynamically retunes the PA output impedance to maintain efficiency across frequencies.
Modulation is implemented via two distinct paths: ASK uses direct PA on/off switching with amplitude shaping for spectral control; FSK alters PLL coefficients for accurate, ultra-clean deviation (Q2/Q100 = 2–100kHz). Configuration occurs either through a 3MHz SPI interface or via dedicated manual-mode pins (FREQ0–FREQ2, SCLK_PWR0, SDI_PWR1).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 280MHz to 450MHz - covers global ISM bands including 315MHz, 433.92MHz, and 434MHz without hardware change. |
| Output Power Range | +14dBm to –14dBm (28dB range in 1dB steps at 5V); +10dBm to –14dBm at 2.1V - enables flexible regulatory compliance and battery-life optimization. |
| Data Rate Support | 50kbps Manchester ASK / 70kbps Manchester FSK - meets emission-bandwidth standards while supporting robust short-range telemetry. |
| Startup Time | <250µs from ENABLE assertion to stable RF output - enables burst transmission for ultra-low average power in sensor networks. |
| Supply Voltage Range | 2.1V–3.6V (direct) or 4.5V–5.5V (with internal regulators) - supports both coin-cell and 5V industrial supply rails. |
| Standby / Shutdown Current | 400nA (standby, 3V mode); 5nA (shutdown, LSHDN high) - critical for multi-year battery operation in remote controls. |
| Regulatory Compliance | FCC Part 15, ETSI EN 300 220 (up to +6dBm EIRP) - validated for certified deployment in North America and EU markets. |
Pinout & Package
The MAX7060ATG+ is housed in a 24-pin, 4mm × 4mm thin QFN package with exposed pad (EP), optimized for RF performance and thermal dissipation in space-constrained automotive and industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ENABLE | Master enable input | Rising-edge activation powers all circuits except PA in ASK mode; required for fast wake-up from standby. |
| PAOUT / PAVOUT | PA RF output / PA bias control | PAOUT connects to antenna matching network; PAVOUT sets output power level via external inductor coupling. |
| CS_DEV / SCLK_PWR0 / SDI_PWR1 | SPI interface signals | Enable full register-based configuration; support 3MHz clock rate and deterministic timing for reliable firmware control. |
| FREQ0–FREQ2 | Manual frequency select inputs | Allow 8 discrete frequency presets without MCU involvement - ideal for simple remote-control PCBs. |
| LSHDN | Low-power shutdown control | Reduces current to 5nA in 3V mode by disabling POR and pullups; must be grounded in 5V mode. |
| DIN / GPO2_MOD | Data input / modulation mode select | DIN accepts ASK/FSK baseband data; GPO2_MOD selects ASK (0) or FSK (1) in manual mode. |
| XTAL1 / XTAL2 | Crystal oscillator terminals | Support 15–16MHz fundamental-mode crystals with 10pF load capacitance - eliminates SAW stability issues. |
| EP (Exposed Pad) | Thermal & RF ground | Must be soldered to solid ground plane for optimal thermal performance, EMI suppression, and PA efficiency. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar ASK/FSK transmitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Silicon Labs Si4010 | Single-chip ASK transmitter with integrated MCU and EEPROM; no external crystal required (internal RC oscillator); lower max output (+13dBm); 24-pin QFN same footprint. | Designed for ultra-low-cost, self-contained remotes with embedded firmware; lacks FSK mode and manual pin control. | Select Si4010 when eliminating external MCU and crystal is prioritized over FSK flexibility and automotive temp range. |
| TI CC1110-CC1111 | Sub-1GHz SoC with integrated 8051 MCU, 32KB flash, and RF transceiver; supports ASK/FSK/GFSK; requires external crystal; 48-pin QFN. | Targeted at protocol-aware systems (e.g., SimpliciTI, proprietary mesh); higher integration but larger footprint and higher BOM cost. | Select CC1110 when protocol stack execution, packet handling, or mesh networking is required alongside RF transmission. |
Compared with Si4010 and CC1110, the MAX7060ATG+ delivers superior frequency agility (280–450MHz continuous tuning), lowest shutdown current (5nA), and true manual-mode operation - making it optimal for cost-sensitive, long-life, automotive-qualified ASK/FSK links where MCU offload or SoC-level integration is unnecessary.

FAQ
What is the minimum supply voltage required for MAX7060ATG+ operation?
The MAX7060ATG+ operates from 2.1V to 3.6V in direct-supply mode, and from 4.5V to 5.5V when using internal regulators. At 2.1V, it delivers +10dBm maximum output power and maintains full functionality including SPI and manual modes. This makes MAX7060ATG+ suitable for single-cell lithium or alkaline battery applications where voltage drops below 2.5V over time.
Does MAX7060ATG+ support both ASK and FSK modulation simultaneously?
No, the MAX7060ATG+ does not support simultaneous ASK and FSK. Modulation mode is selected at runtime: in SPI mode, it is set via register bit MODSEL; in manual mode, it is controlled by the logic level on GPO2_MOD pin (low = ASK, high = FSK). The MAX7060ATG+ is optimized for high-fidelity, dedicated-mode transmission - not dual-modulation concurrency.
How is frequency programmed on the MAX7060ATG+?
Frequency is programmed either via SPI register writes (full 280–450MHz coverage with 1kHz resolution) or using three manual-mode pins (FREQ0–FREQ2) to select one of eight preset frequencies. Both methods configure the fractional-N PLL's programmable divider (range 19–28) and VCO calibration. A single 15–16MHz crystal suffices for the entire band - no VCO bank switching or external tuning elements needed.
What is the purpose of the PAOUT capacitor tuning feature in MAX7060ATG+?
The MAX7060ATG+ includes an on-die programmable capacitor (0–7.75pF in 0.25pF steps) connected in parallel with PAOUT. This capacitor dynamically compensates for antenna impedance variation across frequency, maintaining optimal PA load match and efficiency (>70%) without requiring external tunable components or PCB redesign. It enables true frequency agility in compact form factors.
Is the MAX7060ATG+ qualified for automotive applications?
Yes, the MAX7060ATG+ is explicitly specified for the automotive temperature range (–40°C to +125°C) and carries the "/V" automotive qualification suffix in its ordering part number (e.g., MAX7060ATG/V+). It undergoes 100% testing at +125°C and meets AEC-Q100 stress requirements for reliability in under-hood and cabin-mounted modules.
