Product details
Overview
The 108962-HMC497LP4 from Analog Devices (formerly Hittite Microwave) is a SiGe direct quadrature modulator RFIC designed for wideband digital modulation in RF transmitters. It operates from 100–4000 MHz, delivers +9 dBm P1dB output power, achieves +22 dBm OIP3 linearity, and features –161 dBm/Hz noise floor at 20 MHz offset. It serves as the core modulation stage in cellular base stations and broadband wireless access systems.
For engineers reviewing the 108962-HMC497LP4 datasheet, 108962-HMC497LP4 pinout, 108962-HMC497LP4 application, or 108962-HMC497LP4 equivalent, key selection criteria include its 4×4 mm QFN LP4 package, dual 5 V supply rails (Vcc1/Vcc2), differential I/Q baseband inputs (DC–700 MHz), single-ended 50 Ω RFOUT, and LO drive range of –6 to +6 dBm in single-ended or differential mode.
Technical Context
This RFIC implements a SiGe-based direct-conversion quadrature architecture with integrated I/Q mixers, LO buffer, and RF output amplifier. Its design eliminates image-rejection filters and avoids double upconversion, reducing system complexity and BOM cost.
It supports uncalibrated sideband suppression ≥42 dBc and carrier feedthrough ≤–36 dBm at +25°C, with calibrated performance further improved via external DC offset and phase/amplitude tuning. Baseband input bias is fixed at +1.5 V DC with 90 μA typical bias current per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 100–4000 MHz - enables single-device coverage across UMTS, GSM, CDMA, ISM 900/2400 MHz, and 3.4–4.0 GHz bands. |
| Output P1dB | +9 dBm - sufficient drive level to directly interface with PA stages without intermediate gain blocks in compact transceivers. |
| OIP3 | +22 dBm - ensures high ACLR compliance in W-CDMA and LTE signals with minimal distortion-induced spectral regrowth. |
| Noise Floor | –161 dBm/Hz @ 20 MHz offset - preserves EVM in high-order QAM (e.g., 256-QAM) by minimizing noise contribution to signal constellation. |
| Baseband BW | DC–700 MHz - supports complex waveforms including 100 MHz+ signal bandwidths for 5G NR FR1 and WiMAX. |
| LO Drive | –6 to +6 dBm - accommodates both low-power LO synthesizers and buffered LO sources without external amplification. |
| Supply Voltage | +4.5 to +5.5 V - compatible with standard 5 V system rails; split Vcc1 (79 mA) and Vcc2 (88 mA) enable independent power domain control. |
Pinout & Package
Housed in a 4×4 mm, 24-pin QFN package (LP4) with exposed thermal paddle, the 108962-HMC497LP4 requires RF ground connection to all GND pins (2,5,8,11,12,14,17,19,20,23) and the paddle. The package is MSL1 rated with Sn/Pb (HMC497LP4) or 100% matte Sn (HMC497LP4E) finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 3, 4 | LOP, LON | Differential LO input ports; support single-ended drive via LON only; require DC blocking capacitors and 50 Ω termination. |
| 9, 10 | QN, QP | Differential Q-channel baseband input; high-impedance, biased at +1.5 V DC; nominal 1.6 Vpp differential swing. |
| 16 | RFOUT | Single-ended 50 Ω RF output; requires DC blocking capacitor; no external matching needed. |
| 18 | Vcc1 | Supply for mixer and RF output stage (79 mA @ +5 V); decoupling critical for noise and stability. |
| 21, 22 | IP, IN | Differential I-channel baseband input; identical bias and impedance characteristics as QP/QN. |
| 24 | Vcc2 | Supply for LO buffer stage (88 mA @ +5 V); separate rail minimizes LO-to-RF leakage coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Wide RF bandwidth | 100–4000 MHz continuous coverage - eliminates need for multiple narrowband modulators across multi-band radios. |
| Integrated 50 Ω RFOUT match | Zero external components required on RF output path - reduces layout area and parasitic sensitivity in high-frequency designs. |
| Low-noise SiGe process | –161 dBm/Hz noise floor - enables high dynamic range in receiver-shared transceiver architectures with shared LO. |
| Dual-supply architecture | Separate Vcc1 (mixer/output) and Vcc2 (LO buffer) rails - suppresses supply-induced LO pulling and improves spectral purity. |
| DC-coupled baseband inputs | DC–700 MHz bandwidth with +1.5 V common-mode bias - supports zero-IF and low-IF architectures with baseband DACs or analog I/Q sources. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar direct quadrature modulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADL5375-05 | Wider baseband BW (DC–2 GHz), higher supply current (220 mA), 5×5 mm package. | Better suited for wideband radar or multi-carrier LTE-A where >700 MHz BB BW is required. | Select ADL5375-05 when baseband bandwidth >700 MHz or higher output power (+11 dBm) is mandatory. |
| HMC6301 | Narrower RF range (1.7–2.7 GHz), lower noise floor (–163 dBm/Hz), same LP4 package. | Optimized for 2.6 GHz LTE eNodeB with tighter phase noise and carrier suppression specs. | Choose HMC6301 for 2.6 GHz infrastructure where calibrated carrier suppression <–45 dBm is critical. |
Compared with ADL5375-05 and HMC6301, the 108962-HMC497LP4 offers broader RF coverage (100–4000 MHz) and lower power consumption (168 mA), making it optimal for multi-band portable or cost-sensitive FWA platforms where 700 MHz baseband BW suffices.

FAQ
What is the operating temperature range for the 108962-HMC497LP4?
The 108962-HMC497LP4 is specified for operation from –40°C to +85°C ambient temperature. Its SiGe process and thermal resistance (34°C/W junction-to-lead) ensure stable RF performance across this full industrial range, with calibrated sideband suppression and carrier feedthrough tested at –40°C, +25°C, and +85°C per datasheet characterization.
Does the 108962-HMC497LP4 require external RF matching components?
No, the 108962-HMC497LP4 does not require external RF matching components. Its RFOUT pin is internally matched to 50 Ω, enabling direct connection to a 50 Ω transmission line or filter input. This simplifies PCB layout and eliminates tuning sensitivity in 100–4000 MHz applications.
Can the 108962-HMC497LP4 be driven with a single-ended LO signal?
Yes, the 108962-HMC497LP4 accepts single-ended LO drive via the LON pin (Pin 4), while LOP (Pin 3) is AC-coupled and terminated. The device's LO port supports –6 to +6 dBm single-ended input, with 15 dB return loss typical; differential drive is optional but not required for functional operation.
What baseband input configuration does the 108962-HMC497LP4 support?
The 108962-HMC497LP4 supports fully differential I/Q baseband inputs (IP/IN and QP/QN) with +1.5 V DC common-mode bias and 90 μA typical bias current per channel. It accepts 1.6 Vpp differential swing and operates from DC to 700 MHz, making it compatible with both baseband DACs and analog I/Q sources in zero-IF architectures.
Is the 108962-HMC497LP4 pin-compatible with the HMC497LP4E variant?
Yes, the 108962-HMC497LP4 is mechanically and electrically pin-compatible with the RoHS-compliant HMC497LP4E variant. Both share identical 24-pin LP4 QFN footprint, pin functions, electrical specifications, and thermal pad requirements; only the lead finish (Sn/Pb vs. 100% matte Sn) and MSL reflow profile differ.
