It supports Manchester-encoded data rates up to 50kbps (ASK) and 70kbps (FSK), and is qualified for automotive applications across –40°C to +125°C.
For engineers reviewing the MAX7060ATG/V+T datasheet, MAX7060ATG/V+T pinout, MAX7060ATG/V+T application, or MAX7060ATG/V+T equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, automotive-grade package details, and two confirmed alternative transmitters with documented functional trade-offs.
Technical Context
The MAX7060ATG/V+T implements a crystal-referenced fractional-N PLL architecture with VCO gain of 340MHz/V and loop bandwidth of 300kHz, enabling precise frequency synthesis across its full 280–450MHz range using a single 15–16MHz crystal. Its programmable PA matching capacitor (0–7.75pF in 0.25pF steps) dynamically retunes output impedance to maintain high efficiency during rapid frequency hops.
Modulation is implemented via direct PA on/off switching for ASK (70dB modulation depth, <–24dBc harmonics) and coefficient-based FSK deviation control (Q2–Q100kHz), delivering ultra-clean spectral performance compliant with FCC Part 15 and ETSI EN 300 220 (up to +6dBm EIRP). Configuration occurs via SPI (SCLK_PWR0/SDI_PWR1/CS_DEV) or manual pin-strapping (FREQ0–FREQ2, SCLK_PWR0, SDI_PWR1).

FAQ
What is the operating temperature range for the MAX7060ATG/V+T?
The MAX7060ATG/V+T is qualified for the automotive temperature range of –40°C to +125°C, with full electrical specifications guaranteed across this range. This includes 100% testing of frequency accuracy, output power, and startup time at +125°C - enabling use in engine bay, TPMS, and body control modules where ambient heat exceeds standard commercial-grade limits. The device's TQFN-24 package with exposed pad ensures effective thermal dissipation under continuous operation.
Does the MAX7060ATG/V+T support both ASK and FSK modulation natively?
Yes, the MAX7060ATG/V+T supports both ASK and FSK modulation modes natively. ASK is implemented by switching the PA on/off with excellent on/off ratio (>70dB), while FSK is achieved by dynamically adjusting the fractional-N PLL coefficients to shift carrier frequency with high accuracy (Q2–Q100kHz deviation). The GPO2_MOD pin selects modulation type in manual mode, and register bit configuration enables it in SPI mode - eliminating need for external modulators or discrete switching circuitry.
How does the programmable matching capacitor improve RF performance in the MAX7060ATG/V+T?
The MAX7060ATG/V+T integrates a digitally programmable capacitor (0–7.75pF in 0.25pF steps) in parallel with the PA output. This capacitor dynamically compensates for antenna impedance variation across its 280–450MHz band and over temperature, maintaining high PA efficiency (>75%) and consistent output power without requiring multiple PCB layouts or manual antenna tuning. It enables true frequency-agile operation - critical for FHSS systems and multi-band remote controls.
Can the MAX7060ATG/V+T operate from a single 3.3V supply?
Yes, the MAX7060ATG/V+T operates from a single 2.1V to 3.6V supply in direct mode, supporting common 3.3V logic rails and Li-ion/LiFePO₄ battery systems. At 3.3V, it delivers up to +13dBm output power (PApwr = 0x1E) and maintains full functionality including SPI interface, FSK modulation, and 400nA standby current. No external regulators or level shifters are required - simplifying power architecture for space-constrained remote controls and sensors.
What evaluation resources are available for the MAX7060ATG/V+T?
An official Maxim Integrated evaluation kit (EVAL-MAX7060) is available for the MAX7060ATG/V+T, supporting rapid prototyping of ASK/FSK transmitters at 315MHz and 433.92MHz.
