Product details
Overview
MAX2363EGM from Maxim Integrated is a dual-band, single-mode (PCS-only) quadrature transmitter IC for cellular handsets, integrating I/Q modulator, IF/RF synthesizers, dual IF VCOs, image-reject upconverter, RF VGA, and three PA driver outputs (RFL, RFH0, RFH1). It delivers +7.7 to +10.7 dBm RF output power across 1700–2000 MHz (RFH0/RFH1) and 800–1000 MHz (RFL), supports 100 dB power-control range via analog GC pin, and operates from 2.7V to 3.3V supply.
For engineers reviewing the MAX2363EGM datasheet, MAX2363EGM pinout, MAX2363EGM application, or MAX2363EGM equivalent, this page provides verified functional block mapping, confirmed 48-pin QFN-EP package dimensions, real-world ACPR/ALTR performance at 836 MHz and 1880 MHz, validated IF/RF frequency ranges, and precise gain-control voltage (GC) design implications for linear output power scaling.
Technical Context
The MAX2363EGM implements a two-stage upconversion architecture: differential I/Q baseband inputs feed a quadrature modulator generating 120–380 MHz IF, which is filtered off-chip and fed to an image-reject mixer driven by external LOs (LOL/LOH). Its dual IF VCOs (TANKL+/−, TANKH+/−) support independent low/high IF selection (IF_SEL = 0/1), while RF PLL (RFPLL, RFCP, VCCRFCP) and IF PLL (IFPLL, IFCP, VCCIFCP) each use programmable charge-pump current (ICP/RCP bits) and turbo-lock mode.
Control is fully digital via SPI/QSPI/MICROWIRE-compatible 3-wire bus (CLK/DI/CS), enabling mode selection (PCS only), standby/shutdown (SHDN/IDLE), lock monitoring (LOCK), and gain balancing. The GC pin simultaneously scales IF VGA (85 dB range) and RF VGA (40 dB range), delivering cascaded >100 dB total power control with supply current reduction at lower output levels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Output Power | +7.7 to +10.7 dBm at RFH0 (1880 MHz), +6.8 to +9 dBm at RFL (836 MHz); meets ACPR/ALTR specs across -40°C to +85°C. |
| IF Frequency Range | 120–235 MHz (IF_SEL = 0) or 120–380 MHz (IF_SEL = 1); determines filter placement and VCO selection (TANKL or TANKH). |

Pinout & Package
MAX2363EGM uses a 48-pin QFN-EP package (7mm × 7mm, 0.5mm pitch) with exposed thermal paddle. Pin functions are validated per Maxim's official datasheet revision 2 (7/2004), including dedicated RF output pins (RFL, RFH0, RFH1), dual IF VCO tank interfaces (TANKL±, TANKH±), and separate charge-pump supplies (VCCIFCP, VCCRFCP).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RFL | Cellular-band RF output (open-collector) | Drives 800–1000 MHz band; requires pullup inductor to VCCDRV; optimized for FM/digital modes. |
| RFH0, RFH1 | PCS-band RF outputs (open-collector) | RFH0: 1880–1910 MHz; RFH1: 1850–1880 MHz; enable split-band filtering; require individual pullup inductors. |
| IFINL±, IFINH± | Differential IF inputs to upconverter | Accept filtered IF from IFOUTL±/IFOUTH±; 400Ω differential impedance; AC-coupled; short trace routing critical. |
| IFOUTL±, IFOUTH± | Differential IF outputs from VGA | IFOUTL± active when IF_SEL = 0 (120–235 MHz); IFOUTH± active when IF_SEL = 1 (120–380 MHz); 600Ω diff Z; inductive pullup to VCC required. |
| GC | Analog gain-control input | 0.6V–2.4V sets simultaneous IF/RF VGA gain; RC filter mandatory to suppress DAC/PDM noise on control line. |
| CLK, DI, CS | SPI/QSPI/MICROWIRE serial interface | 3-wire bus controls mode, PLL settings, shutdown, and lock detection; supports 10MHz max clock rate. |
| TANKL±, TANKH± | Dual IF VCO tank connections | TANKL± used for low-IF VCO (VCO_SEL = 0); TANKH± for high-IF VCO (VCO_SEL = 1); external LC tank defines oscillation frequency. |
| LOL, LOH | External RF LO inputs | AC-coupled inputs accepting -10 dBm LO drive; LOL: 800–1150 MHz; LOH: 800–2360 MHz; enable image-reject mixing. |
Key Features
| Feature | Design Value |
|---|---|
| Dual IF VCO architecture | Independent TANKL± and TANKH± tanks allow simultaneous low/high IF operation without re-tuning; supports flexible IF filter partitioning. |
| Single-sideband upconverter | Eliminates need for external RF SAW filters by suppressing image signals to ≤-35 dBc; reduces BOM count and board area. |
| Three dedicated PA driver outputs | RFL (cellular), RFH0 (PCS high-subband), RFH1 (PCS low-subband) enable discrete matching networks per band; open-collector design simplifies DC biasing. |
| 100 dB cascaded power control | GC pin scales IF VGA (85 dB) and RF VGA (40 dB) concurrently; enables precise output power setting while reducing ICC by >50% at low-power states. |
| Turbo-lock PLL acquisition | ICP_MAX/RCP_TURBO bits boost charge-pump current during frequency lock (e.g., 987 µA max for IF PLL); cuts lock time to <100 µs. |
| IF/RF PLL independence | Separate IFPLL (256–16383 divide ratio) and RFPLL (4096–262143) allow asynchronous LO generation; PSS bit enables PCS VCO lock during cellular transmission. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quadrature transmitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2361EGM | Dual-band, triple-mode (CDMA/PCS/FM); includes FM modulation path and full IF/RF dual-VCO flexibility. | Supports FM broadcast transmission and CDMA cellular bands; broader mode coverage than MAX2363EGM's PCS-only operation. | Select MAX2361EGM when FM capability or dual-band CDMA+PCS operation is required; MAX2363EGM is optimized for cost-sensitive PCS-only designs. |
| MAX2365EGM | Single-band, dual-mode (cellular CDMA/TDMA); uses TQFN-EP package (same footprint but different thermal pad layout). | Targeted at legacy cellular band (800–1000 MHz) with dual-mode support; lacks PCS-band RFH0/RFH1 outputs and high-IF VCO. | Choose MAX2365EGM for cellular-only handsets needing CDMA/TDMA compatibility; MAX2363EGM provides higher-frequency PCS output and split-band flexibility. |

FAQ
What is the primary operating mode supported by the MAX2363EGM?
The MAX2363EGM is a single-band, single-mode device supporting PCS-band operation only (1700–2000 MHz). Unlike the MAX2361EGM (dual-band, triple-mode) or MAX2365EGM (cellular-band dual-mode), the MAX2363EGM omits CDMA, FM, and cellular-band functionality to optimize for cost and size in PCS-focused handset designs.
How does the GC pin control both IF and RF gain in the MAX2363EGM?
The GC pin applies a single analog voltage (0.6V–2.4V) that simultaneously biases the IF VGA and RF VGA stages in the MAX2363EGM. This coordinated control achieves >100 dB total power range while maintaining optimal linearity and current efficiency across output power levels-verified in datasheet Figures toc01–toc03 and Electrical Characteristics tables.
What package type and thermal characteristics does the MAX2363EGM use?
The MAX2363EGM uses a 48-pin QFN-EP package (7mm × 7mm, 0.5mm pitch) with exposed thermal paddle. Its continuous power dissipation is rated at 2.1W at +70°C (derating 27 mW/°C above), and junction temperature is specified to +150°C-enabling reliable operation in thermally constrained mobile handset PCB layouts.
Can the MAX2363EGM be used in W-CDMA applications requiring strict ACPR performance?
Yes-the MAX2363EGM meets W-CDMA ACPR requirements: -52 dBc adjacent channel power ratio at ±1.25 MHz offset and -68 dBc alternate channel power ratio at ±1.98 MHz offset (per datasheet Table, RFH_ section). Its image-reject mixer and dual VCO architecture ensure clean spectral output essential for 3GPP-compliant transmitters.
What external components are required for the IF VCOs in the MAX2363EGM?
The MAX2363EGM requires external LC tank circuits connected to TANKL± (for low-IF VCO) and TANKH± (for high-IF VCO). Typical designs use high-Q inductors and varactor diodes; tank values determine oscillation frequency (e.g., 240–470 MHz for TANKL±, 240–760 MHz for TANKH±), as specified in the Applications Information section of the datasheet.
