Product details
Overview
HMC697LP4E from Analog Devices (formerly Hittite Microwave) is a SiGe wideband direct quadrature modulator IC operating from 200 MHz to 4000 MHz, delivering +8 dBm typical output P1dB, −165 dBm/Hz noise floor, and +22 dBm typical OIP3. It serves as the RF upconversion stage in digital transmitters for cellular base stations, WiMAX, and ISM-band transceivers.
For engineers reviewing the HMC697LP4E datasheet, HMC697LP4E pinout, HMC697LP4E application, or HMC697LP4E equivalent, key selection criteria include its uncalibrated sideband suppression (≥42 dBc), carrier feedthrough (≤−33 dBm), LO input power range (−6 to +6 dBm), single-ended or differential LO drive capability, and 4×4 mm 24-lead QFN package with integrated 50 Ω RF output match.
Technical Context
The HMC697LP4E implements a SiGe-based I/Q modulator architecture with fully differential baseband inputs (IP/IN, QP/QN) biased at +1.5 V DC and accepting 1.6 VPP differential AC signals. Its RF output is DC-coupled and internally matched to 50 Ω without external matching components.
LO port supports both single-ended (via LOP) and differential (LOP/LOM) drive modes across 200–4000 MHz; supply rails Vcc1 (+5 V, 79 mA) and Vcc2 (+5 V, 88 mA) are independently decoupled. Carrier and sideband suppression performance is specified both uncalibrated and calibrated, with worst-case over temperature (−40 °C to +85 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 200–4000 MHz RF; enables single-modulator coverage of GSM, UMTS, LTE, WiMAX, and ISM bands. |
| Output P1dB | +8 dBm typical; sufficient for direct drive of PA stages without intermediate gain in compact transmitters. |
| Output IP3 | +22 dBm typical; supports high-linearity modulation schemes including 64-QAM and W-CDMA with low ACPR. |
| Noise Floor | −165 dBm/Hz typical @ 20 MHz offset; minimizes EVM degradation in wideband OFDM systems. |
| Sideband Suppression | 42–45 dBc uncalibrated; reduces image power without calibration circuitry in cost-sensitive designs. |
| Carrier Feedthrough | −33 to −40 dBm uncalibrated; limits DC offset-induced LO leakage into RF output path. |
| LO Input Power | −6 to +6 dBm; compatible with low-power synthesizers and eliminates need for LO buffer amplifiers. |
| Supply Voltage | +4.5 to +5.5 V; operates robustly across industrial voltage tolerances with total current draw of 168 mA. |
Pinout & Package
Package: 24-lead 4×4 mm QFN with exposed ground paddle (RoHS-compliant matte Sn finish, MSL1, max reflow 260 °C). Pinout validated per official HMC697LP4E pin description table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 6, 7, 13, 15 | N/C | No internal connection; must remain unconnected per design. |
| 2, 5, 8, 11, 12, 14, 17, 19, 20, 23 | GND | RF/DC ground terminals; require low-inductance vias to solid ground plane. |
| 3, 4 | LOP, LON | Differential LO input; supports single-ended drive on LOP with LON grounded. |
| 9, 10 | QN, QP | Differential Q-baseband input; high-impedance, DC-biased at +1.5 V, accepts 1.6 VPP signal. |
| 16 | RFOUT | Single-ended 50 Ω-matched RF output; DC-coupled, requires external AC-blocking capacitor. |
| 18 | Vcc1 | Supply for mixer and output stages (79 mA @ +5 V); requires local 100 pF + 4.7 µF decoupling. |
| 21, 22 | IP, IN | Differential I-baseband input; identical bias and signal requirements as Q channel. |
| 24 | Vcc2 | Supply for LO buffer stage (88 mA @ +5 V); independent decoupling required. |
Key Features
| Feature | Design Value |
|---|---|
| Wide RF bandwidth | 200–4000 MHz continuous coverage eliminates band-switching hardware in multi-standard radios. |
| Integrated 50 Ω RF output match | Removes external matching network, reducing BOM count and PCB area in SMT layouts. |
| Low-noise SiGe process | −165 dBm/Hz noise floor enables high-EVM transmission in 20 MHz LTE and 80 MHz WiGig channels. |
| Dual-supply architecture | Separate Vcc1/Vcc2 rails isolate LO stage from mixer/output noise coupling and improve PSRR. |
| Flexible LO interface | Supports −6 to +6 dBm single-ended or differential LO drive, easing integration with PLL/VCO sources. |
| Uncalibrated image rejection | ≥42 dBc sideband suppression without external calibration circuitry lowers system complexity and cost. |

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 | 500–4000 MHz range; +23 dBm OIP3; requires external 50 Ω RF match; higher supply current (220 mA). | Better linearity but needs matching network and more board space; suited for high-ACLR LTE eNodeB. | Select ADL5375-05 when OIP3 >+22.5 dBm is mandatory and layout allows external matching. |
| TRF3705 | 400–4000 MHz; +19 dBm OIP3; −162 dBm/Hz noise floor; integrated LO divider; 3.3 V supply only. | Lower power consumption and built-in frequency division, but reduced linearity and noise performance vs. HMC697LP4E. | Choose TRF3705 for battery-powered or 3.3 V systems where moderate EVM suffices and LO division is needed. |
Compared with ADL5375-05 and TRF3705, the HMC697LP4E offers superior uncalibrated sideband suppression (42–45 dBc) and best-in-class noise floor (−165 dBm/Hz), making it optimal for wideband OFDM systems where calibration overhead is undesirable and spectral purity is critical.

FAQ
What is the operating temperature range for the HMC697LP4E?
The HMC697LP4E is rated for operation from −40 °C to +85 °C ambient temperature. Performance specifications-including sideband suppression, carrier feedthrough, and output power-are guaranteed across this full industrial range under calibrated and uncalibrated conditions, with worst-case data plotted at −40 °C, +25 °C, and +85 °C.
Does the HMC697LP4E require external RF matching components?
No, the HMC697LP4E features an internally matched 50 Ω single-ended RF output (Pin 16). No external matching network is required-only an AC-blocking capacitor is needed at the RFOUT pin. This simplifies layout and reduces bill-of-materials cost compared to modulators requiring discrete matching.
Can the HMC697LP4E be driven with a single-ended LO signal?
Yes, the HMC697LP4E supports single-ended LO drive via Pin 3 (LOP), with Pin 4 (LON) grounded. The device's LO port is designed for −6 to +6 dBm input power in either single-ended or differential mode, eliminating the need for external baluns or LO buffers in many architectures.
What baseband input voltage levels are recommended for the HMC697LP4E?
The HMC697LP4E baseband inputs (IP/IN, QP/QN) require +1.5 V DC bias (±0.1 V) and accept 1.6 VPP differential AC signals. The differential input impedance is high, and input capacitance is 4.5 pF (de-embedded), enabling direct interface with high-speed DACs without level-shifting circuitry.
Is the HMC697LP4E pin-compatible with the HMC697LP4?
Yes, the HMC697LP4E is a RoHS-compliant drop-in replacement for the HMC697LP4. Both share identical 24-lead 4×4 mm QFN footprint, pinout, electrical specifications, and thermal characteristics-only the lead finish differs (matte Sn vs. Sn/Pb) and MSL rating reflects reflow profile differences (260 °C vs. 235 °C peak).
