Product details
Overview
HMC862LP3E from Analog Devices (formerly Hittite Microwave) is a low-noise, programmable RF frequency divider IC with N = 1, 2, 4, 8 division ratios, operating from 0.1 GHz to 15 GHz input frequency, delivering ≤ –153 dBc/Hz SSB phase noise at 100 kHz offset (Fin = 6 GHz, Pin = 0 dBm), and housed in a 16-lead 3×3 mm leadless surface-mount package. It serves as a core clock conditioning element in wideband microwave transceivers.
For engineers reviewing the HMC862LP3E datasheet, HMC862LP3E pinout, HMC862LP3E application, or HMC862LP3E equivalent, this device is selected for high-frequency PLLs, satellite modems, and test instrumentation where ultra-low phase noise, wideband operation, and flexible integer division are critical design requirements.
Technical Context
The HMC862LP3E implements a broadband static CMOS prescaler architecture with differential RF input (IN/NIN) and complementary RF output (OUT/NOUT), supporting both single-ended and differential operation. Its three CMOS-compatible control bits (S0–S2) directly select division ratio via a verified truth table without internal logic sequencing or lock detection.
It features dual 5 V analog supplies (Vcc1/Vcc2), on-chip biasing optimized for 0.1–15 GHz operation, and requires DC blocking on all RF ports. Phase noise performance is maintained across –40 °C to +85 °C, with thermal resistance of 33 °C/W (junction-to-ground paddle).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Frequency Range | 0.1 GHz to 15 GHz - supports full-band microwave signal conditioning without external band switching. |
| Division Ratios | N = 1, 2, 4, 8 - selectable via three logic inputs; no internal divider chain reconfiguration latency. |
| SSB Phase Noise | –153 dBc/Hz @ 100 kHz offset (Fin = 6 GHz, Pin = 0 dBm) - enables high-order QAM and low-EVM systems. |
| RF Input Power Range | –10 dBm to +10 dBm (N = 1, Fin < 8 GHz); –10 dBm to 0 dBm (N = 1, Fin > 8 GHz) - accommodates variable-level LO sources. |
| Output Power | –2 to +3 dBm (N = 1); ~2 dBm (N = 2, 4, 8) - drives 50 Ω loads directly without amplification in most IF/LO paths. |
| Supply Voltage | +4.75 V to +5.25 V - compatible with standard 5 V system rails; dual Vcc pins reduce supply impedance. |
| Operating Temperature | –40 °C to +85 °C - qualified for military-grade and outdoor wireless infrastructure environments. |
Pinout & Package
16-lead 3×3 mm leadless plastic package (MSL1, RoHS-compliant, matte Sn finish) with exposed ground paddle requiring solder connection to PCB RF ground plane per Hittite Application Note land pattern guidance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 8, 9, 12, 14, 15 | GND | DC and RF ground reference; backside paddle must be soldered to PCB ground for thermal and EMI integrity. |
| 2 | IN | Primary RF input; requires external DC blocking capacitor for AC-coupled signal injection. |
| 3 | NIN | Differential RF input (180° out-of-phase with IN); AC-grounded for single-ended use; DC-blocked for differential mode. |
| 5–7 | S0, S1, S2 | CMOS-compatible division ratio control bits; logic levels 0–0.4 V (low), 3–5 V (high); Vcc applied before logic. |
| 10 | NOUT | Complementary divided output (180° out-of-phase with OUT); requires DC blocking for AC coupling. |
| 11 | OUT | Main RF output port; delivers divided signal; requires DC blocking capacitor for interface to next stage. |
| 13, 16 | Vcc1, Vcc2 | Dual 5 V analog supply inputs; both must be connected to low-noise +5 V rail to ensure stable high-frequency operation. |
Key Features
| Feature | Design Value |
|---|---|

| Programmable N = 1, 2, 4, 8 | Hardware-selectable ratios allow real-time LO tuning in multi-standard radios without firmware overhead. |
| Dual RF outputs (OUT/NOUT) | Provides differential drive capability for balanced mixers or I/Q modulators without external balun. |
| Exposed ground paddle thermal path | 33 °C/W junction-to-ground thermal resistance sustains 162 mA max current at +85 °C ambient. |

FAQ
What is the maximum input frequency supported by the HMC862LP3E?
The HMC862LP3E supports an RF input frequency range from 0.1 GHz to 15 GHz, verified under sine wave or square wave excitation per datasheet conditions. Operation above 15 GHz is not characterized or guaranteed, and input power limits tighten above 8 GHz to maintain linearity and phase noise integrity. The HMC862LP3E must be used within this specified band for compliant performance.
Does the HMC862LP3E require external DC blocking capacitors?
Yes, the HMC862LP3E requires external DC blocking capacitors on all RF ports: IN (pin 2), NIN (pin 3), OUT (pin 11), and NOUT (pin 10). This is explicitly mandated in the Pin Description section and functional schematics to prevent DC bias disruption and ensure proper AC-coupled RF signal path integrity. The HMC862LP3E itself contains no internal DC blocking.
How is the division ratio programmed on the HMC862LP3E?
The HMC862LP3E uses three CMOS-compatible digital control inputs - S0 (pin 5), S1 (pin 6), and S2 (pin 7) - to select division ratio N = 1, 2, 4, or 8 per a defined truth table. Logic high is 3–5 V; logic low is 0–0.4 V. Vcc1 and Vcc2 must be applied before asserting control bits. The HMC862LP3E performs static division without internal state machines or serial interfaces.
What is the phase noise performance of the HMC862LP3E at 10 GHz input?
While the datasheet specifies –153 dBc/Hz SSB phase noise at 100 kHz offset for Fin = 6 GHz, it does not provide measured data at 10 GHz. Performance degrades with increasing input frequency due to active device limitations; users should consult the "Phase Noise vs. Frequency" plot (page 4–2) showing ~–148 dBc/Hz typical at 10 GHz/100 kHz. The HMC862LP3E retains usable phase noise across its full 15 GHz range but is optimized near 6 GHz.
Is the HMC862LP3E pin-compatible with any newer Analog Devices equivalents?
No documented pin-compatible replacement exists for the HMC862LP3E in Analog Devices' current portfolio. The HMC1033LP5E shares the same 3×3 mm package footprint and pinout for GND, Vcc, IN, OUT, and control bits, but differs in NIN/NOUT functionality and biasing - making it a functional alternative, not a drop-in replacement. The HMC862LP3E remains the only device qualified for its exact specification set.
